Product Introduction

Overview

The MC74HC245ADW, produced by onsemi, is a high-performance silicon-gate CMOS octal 3-state noninverting bus transceiver. This device is identical in pinout to the LS245 and is designed for 2-way asynchronous communication between data buses. It features an active-low Output Enable pin that places the I/O ports into high-impedance states, and a Direction control that determines the data flow direction between buses A and B. The MC74HC245ADW is compatible with standard CMOS outputs and, with external pull-up resistors, can also interface with LSTTL outputs.
