PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 643

DESCRIPTION

The 74HC643 is an advanced high-speed CMOS

OCTAL

BUS

TRANSCEIVER

(3-STATE)

fabricated with silicon gate C2MOS technology.

This IC is intended for two-way asynchronous

communication between data buses, and the

direction of data transmission is determined by

DIR input. The enable input G can be used to

disable the device so that the buses are effectively

isolated.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
