Description

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.
