Overview

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Noninverting Bus Transceiver High–Performance Silicon–Gate CMOS The MC54/74HC245A is identical in pinout to the LS245.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC245A 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.
