Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

NC7SZD384 1-Bit Low Power Bus Switch with Level Shifting
NC7SZD384
1-Bit Low Power Bus Switch with Level Shifting
General Description
The NC7SZD384 provides 1-bit of high-speed CMOS TTL-com-
patible bus switch. The low on resistance of the switch allows
inputs to be connected to outputs with minimal propagation
delay and without generating additional ground bounce noise.
The device is organized as a 1-bit switch with a bus enable (OE)
signal. When OE is LOW, the switch is on and Port A is con-
nected to Port B. When OE is HIGH, the switch is open and a
high-impedance state exists between the two ports. Reduced
voltage drive to the gate of the FET switch permits nominal level
shifting of 5V to 3.3V through the switch.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions (Note 3)
Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety
of the device cannot be guaranteed. The device should not be operated at these lim-
its. The parametric values defined in the Electrical Characteristics tables are not
guaranteed at the absolute maximum ratings. The “Recommended Operating Condi-
tions” table will define the conditions for actual device operation.
Note 2: The input and output negative voltage ratings may be exceeded if the input
and output diode current ratings are observed.
Note 3: Unused inputs must be held HIGH or LOW. They may not float.

Note 5: Measured by the voltage drop between A and B pins at the indicated current through the switch. On Resistance is determined by the lower of the voltages on the two (A
or B) pins.
Note 6: Per TTL driven input (VIN
3.4V, control input only). A and B pins do not contribute to ICC.
