TECHNICAL DATA KK74HCT245A Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS The KK74HCT245A 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 KK74HCT245A 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
