IN74AC640 Octal 3-State Inverting Bus Transceiver

TECHNICAL DATA IN74AC640 Octal 3-State Inverting Bus Transceiver High-Speed Silicon-Gate CMOS The IN74AC640 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 IN74AC640 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.
