MM74HC245A Octal 3-STATE Transceiver
General Description
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 TTL circuits.
This device has an active LOW enable input G and a direction control input, DIR.
When DIR is HIGH, data flows from the ...
