SN74AHC138NS TI Decoder/Demultiplexer | 3-to-8 Line | 2V to 5.5V, -40°C to 125°C

Product Overview

The SN74AHC138NS is a high-performance 3-to-8 line decoder/demultiplexer from Texas Instruments, designed for low-power and high-speed applications. It operates over a wide voltage range of 2V to 5.5V, making it suitable for battery-powered and industrial systems. The device features three enable inputs (G1, G2A, G2B) for flexible control, and it can be used as a demultiplexer by connecting one of the enable inputs as the data input. The SN74AHC138NS is available in the SOIC-16 package (NS suffix) and is characterized for operation from -40°C to +125°C.
