Part Number : 74HC245
Function : 74HC245, MM74HC245 / Octal 3-STATE Transceiver
Manufacturers : Fairchild Semiconductor
Pinouts : 
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.
