DESCRIPTION/ORDERING INFORMATION
The TCA9406 is a dual bidirectional I2C-Bus and SMBus Voltage-Level translator with enable (OE) Input. 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.

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 kΩpullup 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.

PRINCIPLES OF OPERATION
Application Notes
The TCA9406 A-Port I/O has open-drain outputs with an internal 10-kΩpullup resistor to VCCA, and B-Port I/O
has an internal 10-kΩpullup 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-kΩresistors). 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 µA 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.

Integrated Pullup Resistors on the I/Os (A-Ports/B-Ports)
Each A-port I/O has an internal 10-kΩpullup resistor to VCCA, and each B-port I/O has an internal 10-kΩpullup
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-kΩresistors). 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.

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.
