DESCRIPTION

The 74HC7640 is an advanced high-speed CMOS

disable the device so that the buses are effectively

isolated. This device have hysteresis

characteristics with each input so can be used as

OCTAL

BUS

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

DIR input. The enable input G can be used to

a line receiver, etc.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
