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

The SL74HC245 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 SL74HC245 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.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 mA

• High Noise Immunity Characteristic of CMOS Devices
