SN74HC138QDRG4Q1 TI Decoder/Demux | 16-SOIC | 3-to-8 Line, -40°C to 125°C

Product Overview

The SN74HC138QDRG4Q1 is a high-performance 3-to-8 line decoder/demultiplexer from Texas Instruments, designed for automotive and industrial applications. It features three binary select inputs (A0, A1, A2) and three enable inputs (G1, G2A, G2B) to provide eight mutually exclusive active-low outputs (Y0–Y7). The device is housed in a 16-pin SOIC package and operates over a wide temperature range of -40°C to 125°C, making it suitable for harsh environments.
