Product Introduction

Overview

The CD74HCT151MT is a high-speed CMOS logic 8-input digital multiplexer produced by Texas Instruments. This device is part of the 74HCT series, which is compatible with TTL (Transistor-Transistor Logic) input levels. The CD74HCT151MT features three binary control inputs (A, B, and C) and an active low enable (G) input, allowing it to select one of eight channels. The outputs are provided in both inverting (W) and non-inverting (Y) forms.

This multiplexer operates over a wide temperature range of -55°C to 125°C, making it suitable for various environmental conditions. It is available in a SOIC (Small Outline Integrated Circuit) package, which is compact and suitable for modern electronic designs.
