TECHNICAL DATA

KK74AC245

Octal 3-State Noninverting

Bus Transceiver

High-Speed Silicon-Gate CMOS

The KK74AC245 is identical in pinout to the LS/ALS245,

HC/HCT245. The device inputs are compatible with standard CMOS

outputs; with pullup resistors, they are compatible with LS/ALS outputs.

The KK74AC245 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 µA; 0.1 µA @ 25°C

High Noise Immunity Characteristic of CMOS Devices

Outputs Source/Sink 24 mA
