74LCX373
Low Voltage Octal Transparent Latch
with 5V Tolerant Inputs and Outputs
General Description
The LCX373 consists of eight latches with 3-STATE outputs for
bus organized system applications. The device is designed for
low voltage (3.3V or 2.5V) V
CC
applications with capability of
interfacing to a 5V signal environment.
The LCX373 is fabricated with an advanced CMOS technology
to achieve high speed operation while maintaining CMOS low
power dissipation.
