SEMICONDUCTOR TECHNICAL DATA

High–Performance Silicon–Gate CMOS

J SUFFIX

CERAMIC PACKAGE

CASE 732–03

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.
