DESCRIPTION

The 74HC643 is an advanced high-speed CMOS

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.

OCTAL

TRANSCEIVER

(3-STATE)

fabricated with silicon gate C MOS technology.

This IC is intended for two-way asynchronous

communication between data buses, and the

direction of data transmission is determined by

PIN CONNECTION AND IEC LOGIC SYMBOLS
