MC74HC138ADG Description

Short technical summary and product information.

The MC74HC138ADG from ON Semiconductor is a versatile 1-of-8 decoder/demultiplexer designed for high-performance applications. This device decodes a three-bit address into one of eight active-low outputs, featuring three chip select inputs for flexible control.

 

With an operating voltage range of 2.0V to 6.0V, the MC74HC138ADG is compatible with CMOS, NMOS, and TTL logic levels. It offers an output drive capability of 10 LSTTL loads and exhibits high noise immunity characteristic of CMOS devices. The device operates across a wide temperature range of -55°C to +125°C.

 

Packaged in a 16-SOIC surface-mount configuration, the MC74HC138ADG is suitable for various electronic designs. Its features include low input current and compliance with JEDEC Standard No. 7A. The device is also Pb-free, halogen-free, and RoHS compliant.

 

This decoder/demultiplexer is ideal for applications requiring address decoding, data demultiplexing, and chip selection functions in digital systems.
