Octal 3-state Bus Transceiver High-speed Silicon-gate Cmos

The KK74AC643 is identical in pinout to the LS/ALS643, HC/HCT643. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. The KK74AC643 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. Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A; o.1 A @ 25C High Noise Immunity Characteristic of CMOS Devices Outputs Source/Sink 24 mA By Kodenshi Korea Corp.
