Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com 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 Semiconductors 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.

The device is byte controlled. The flip-flops CC appear to be transparent to the data when the Latch enable 3.6V tolerant inputs and outputs (LE) is HIGH. When LE is LOW, the data that meets the 26: series resistors in outputs setup time is latched. Data appears on the bus when the t (I to O ) Output Enable (OE) is LOW. When OE is HIGH, the out- PD n n puts are in a high impedance state. 3.3 ns max for 3.0V to 3.6V V CC The VCX162373 is also designed with 26: resistors in the Power-off high impedance inputs and outputs outputs. This design reduces line noise in applications Support live insertion and withdrawal (Note 1) such as memory address drivers, clock drivers and bus Static Drive (I /I ) transceivers/transmitters. OH OL r12 mA 3.0V V The 74VCX162373 is designed for low voltage (1.4V to CC 3.6V) V applications with I/O compatibility up to 3.6V. CC Uses proprietary noise/EMI reduction circuitry The 74VCX162373 is fabricated with an advanced CMOS Latch-up performance exceeds 300 mA technology to achieve high speed operation while maintain- ESD performance: ing low CMOS power dissipation. Human body model 2000V Machine model 200V Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to V through a pull-up resistor the minimum CC value of the resistor is determined by the current-sourcing capability of the driver.
