It is operational from 1.65 V to 3.6 V on A-Port and 2.3 V to 5.5 V on B-port. Enable (OE) input is referenced to VCCA with a maximum input voltage tolerance of 4.6 V. The TCA9406 can operate up to 24Mbps in push pull mode and 2Mbps with open drain mod. Its compatible with a standard I2C bus 100 kHz, 400 kHz and 1 MHz at both sides of A-Port and B-Port. 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Copyright (c) 2010, Texas Instruments Incorporated TCA9406 SCPS221 - JULY 2010 www.ti.com With the standard I2C bus system, it needs pull-up resistors to provide logic HIGH levels on the translator bus. The TCA9406 is an open-drain bus level configuration of the I2C-bus. The value of pullup resistors depends on the system, but each side of the translator must have pull-up resistors and TCA9406 already has 10 k pullup resistors on each side and it allows to add additional external pull-up resistors. It can work with standard-mode, fast-mode and fast mode plus I2C-bus devices in additional to SMBus. The TCA9406 is not a bus buffer like the PCA9515A and PCA9517. It provides both level translation and physically isolates the capacitance to either side of the bus when both sides are connected. The Ioff feature can be utilized to isolate the bus into high impedance when using the power supply to off the either VCCA or VCCB. The Enable (OE) should be tied to GND through a pulldown resistor to ensure the high-impedance state during power up or power down. The minimum value of the resistor is determined by the current-sourcing capability of the driver.

JULY 2010 www.ti.com PRINCIPLES OF OPERATION Application Notes The TCA9406 A-Port I/O has open-drain outputs with an internal 10-k pullup resistor to VCCA, and B-Port I/O has an internal 10-k pullup resistor to VCCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O to VCCA or VCCB (in parallel with the internal 10-k resistors). Adding lower value pullup resistors changes VOL levels. When the OE pin is set low, the internal pullups of the TCA9406 are disabled for power saving caused by pullup resistors. Figure 1. Typical Design Example The TCA6406 has a VCC isolation feature known as Ioff partial power down and backdrive protection. If a cable is connected, and the connected external system is still powered own, the system can be put into standby mode by shutting down the power rail. In this state, the TCA6406 has a leakage current of approximately 2 A caused by current flow from powered-on system. Power Up, Power Down One advantage of the TCA9406 translator is that either power supply can be ramped up first. Another advantage is that either power supply can be set to 0 V, and the outputs are in high-impedance state. The recommended power up sequence is: 1. Apply power to the first VCC and apply the second VCC 2. Drive the OE input high to enable the device The recommended power down sequence is: 1. Drive OE input low to disable the device 2. Switch Off the power from either VCC and remove power from other VCC. Enable/Disable The TCA9406 han an OE input that is used to disable the device by setting OE low, which place all I/Os in the high-impedance state. The control OE is referenced to the VCCA supply. A pulldown resistor tying OE to ground should be used to ensure that bus contention, excessive currents, or oscillations do not occur during power up and power down. The value of resistor is based upon the current sinking capability of the device. 10 Submit Documentation Feedback Copyright (c) 2010, Texas Instruments Incorporated Product Folder Link(s): TCA9406 TCA9406 www.ti.com SCPS221 - JULY 2010 Integrated Pullup Resistors on the I/Os (A-Ports/B-Ports) Each A-port I/O has an internal 10-k pullup resistor to VCCA, and each B-port I/O has an internal 10-k pullup resistor to VCCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O to VCCA or VCCB (in parallel with the internal 10-k resistors). Adding lower value pull-up resistors may effect VOL levels, however. The internal pullups of the PCA9406 are disabled when the OE pin is low.

POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 D: Max = 1.918 mm, Min =1.858 mm E: Max = 0.918 mm, Min =0.858 mm IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as "components") are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI's terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers' products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers' products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
