Octal 3-State Noninverting Bus Transceiver

High-Performance Silicon-Gate CMOS

The SL74HCT245 is identical in pinout to the LS/ALS245.This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.

The SL74HCT245 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.

• TTL/NMOS Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 4.5 to 5.5 V

• Low Input Current: 1.0 μA
