MC74HC245A Octal 3-State Noninverting Bus Transceiver High−Performance Silicon−Gate CMOS The MC74HC245A 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 HC245A 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.
Features • Output Drive Capability: 15 LSTTL Loads • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltag...
