CD74HC238M TI Decoder/Demultiplexer | 16-SOIC | 3-to-8 Line, 2V-6V

Product Overview

The CD74HC238M from Texas Instruments is a high-speed CMOS 3-to-8 line decoder/demultiplexer. 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). When the device is enabled, the outputs are the complement of the selected input combination. The CD74HC238M is available in a 16-SOIC package, making it suitable for space-constrained designs.
