SEMICONDUCTOR TECHNICAL DATA

High–Performance Silicon–Gate CMOS

J SUFFIX

CERAMIC PACKAGE

CASE 732–03

The MC54/74HC640A is identical in pinout to the LS640. The device

inputs are compatible with standard CMOS outputs; with pullup resistors,

they are compatible with LSTTL outputs.

The HC640A is a 3–state transceiver that is used for 2–way asynchronous

communication between data buses. The device has an active–low Output

Enable pin, which is used to place the I/O ports into high–impedance states.

The Direction control determines whether data flows from A to B or from B

to A.
