SN74AHC139NS TI Decoder/Demultiplexer | 2-to-4 Line | 2V-5.5V, -24mA Output

Product Overview

The SN74AHC139NS is a high-speed dual 2-to-4 line decoder/demultiplexer from Texas Instruments, fabricated using advanced AHC (Advanced High-Speed CMOS) technology. It operates over a wide supply voltage range of 2V to 5.5V, making it suitable for battery-powered and industrial applications. The device features two independent decoders, each with active-low enables and outputs, providing flexibility in address decoding and data routing. Housed in an SOP-16 package, the SN74AHC139NS offers low power consumption and high noise immunity, ideal for modern digital systems.
