Product Introduction

Overview

The SN74HC138PWRG4 is a 3-Line to 8-Line Decoder/Demultiplexer produced by Texas Instruments. This device is designed for high-performance memory-decoding and data-routing applications, particularly where short propagation delay times are crucial. It is part of the SNx4HC138 family, which is targeted specifically for high-speed memory decoders and data-transmission systems. The SN74HC138PWRG4 is available in a TSSOP (PW) package with 16 pins and operates over a wide temperature range of -40°C to 85°C.
