TECHNICAL DATA

KK74AC640

Octal 3-State Inverting

Bus Transceiver

High-Speed Silicon-Gate CMOS

The KK74AC640 is identical in pinout to the LS/ALS640,

HC/HCT640. The device inputs are compatible with standard CMOS

outputs; with pullup resistors, they are compatible with LS/ALS outputs.

The KK74AC640 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.
