Octal 3-State Bus Transceiver

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