CD74HC238M Description

Short technical summary and product information.

CD74HC238M is a single 3-to-8 line decoder/demultiplexer from Texas Instruments designed for high-speed CMOS logic applications. The device accepts three binary address inputs and provides eight mutually exclusive active-high outputs, making it suitable for memory address decoding and data demultiplexing.

 

The IC operates from a single 2V to 6V supply with a typical current consumption of 5.2mA. It is specified over the full industrial temperature range of -55°C to 125°C. The CD74HC238M contains one independent 3:8 decoding circuit and uses standard CMOS technology.

 

The decoder is offered in a 16-SOIC surface-mount package, suitable for space-constrained PCB layouts. Typical applications include memory decoding, port expansion, and digital demultiplexing in microcontroller-based systems.
