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 betwe...
