The MM74HC245A 3-STATE bidirectional buffer utilizes
advanced silicon-gate CMOS technology, and is intended
for two-way asynchronous communication between data
buses. It has high drive current outputs which enable high
speed operation even when driving large bus capacitances.
This circuit possesses the low power consumption
and high noise immunity usually associated with CMOS circuitry,
yet has speeds comparable to low power Schottky
