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.
