TECHNICAL DATA KK74HC245A Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS The KK74HC245A is identical in pinout to the LS/ALS245.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
The KK74HC245A is a 3-state noninverting 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.
