TECHNICAL DATA

KK74ACT245

Octal 3-State Noninverting

Bus Transceiver

High-Speed Silicon-Gate CMOS

The KK74ACT245 is identical in pinout to the LS/ALS245,

HC/HCT245. The KK74ACT245 may be used as a level converter for

interfacing TTL or NMOS outputs to High Speed CMOS inputs.

The KK74ACT245 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.
