74HC245 データシート - ON Semiconductor

Octal 3−State Noninverting Bus Transceiver
High−Performance Silicon−Gate CMOS

The 74HC245 is identical in pinout to the LS245. The device inputs are compatible with standard CMOS outputs; with pull−up resistors, they are compatible with LSTTL outputs.
The HC245 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.
