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.
