CD74AC138M Description

Short technical summary and product information.

The Texas Instruments CD74AC138M is an active 3-line to 8-line inverting decoder/demultiplexer from the AC technology family. Designed for high-performance memory decoding and data-routing applications, it offers very short propagation delay times.

 

This device features a wide operating voltage range of 1.5V to 5.5V, ensuring compatibility with various system designs. It provides balanced noise immunity and operates at speeds comparable to bipolar logic families but with significantly reduced power consumption. The CD74AC138M incorporates three enable inputs, simplifying cascading and data reception.

 

With an operating temperature range of -55°C to 125°C, this decoder/demultiplexer is suitable for demanding environments. It offers ±24mA output drive current and can fan out to 15 devices. The component is built on a SCR-latchup-resistant CMOS process and exceeds 2kV ESD protection per MIL-STD-883, method 3015.

 

The CD74AC138M is available in a 16-SOIC package, designed for surface mount applications. Its specific package dimensions are 16-SOIC (0.154", 3.90mm Width).
