IN74AC643, Octal Bus Transceiver
TECHNICAL DATA Octal 3-State Bus Transceiver High-Speed Silicon-Gate CMOS The IN74AC643 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 IN74AC643 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.
