CD74HC238NSR TI Decoder/Demultiplexer | 16-SO | 3-to-8 Line, 2V-6V

Product Overview

The CD74HC238NSR is a high-speed CMOS 3-to-8 line decoder/demultiplexer from Texas Instruments. It is designed for memory decoding and data routing applications where low power dissipation and high noise immunity are required. The device features three binary select inputs (A0, A1, A2) and three enable inputs (E1, E2, E3), providing flexibility in enabling and disabling the outputs. The CD74HC238NSR is available in a 16-pin SOIC package (NSR suffix) and operates over a wide voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications.
