Product Introduction

Overview

The MC74HC373ADWG, produced by onsemi, is an Octal 3-State Non-Inverting Transparent Latch. This device is part of the high-performance silicon-gate CMOS family and is identical in pinout to the LS373. It features eight transparent D-type latches, making it suitable for a variety of digital logic applications. The device is compatible with standard CMOS outputs and, with pull-up resistors, can also interface with LSTTL outputs. The MC74HCT373A version can be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs.
