Each section selects one of four active-low outputs based on a 2-bit address input, making it a go-to part for memory-mapped I/O decoding, LED matrix row selection, or routing a data stream to one of four destinations. Outputs source or sink 8mA each — enough to drive a standard logic input or a low-current LED directly. ## Temperature range and package for bench and field The 16-SOIC package (3.90mm body width) is a hand-solderable surface-mount footprint; with a fine-tip iron and some flux, a hobbyist can breadboard it on an adapter board without a reflow oven.","metaTitle":"SN74AHC139D Texas Instruments 74AHC Decoder/Demux, 2V-5.5V","metaDescription":"SN74AHC139D dual 2:4 decoder/demultiplexer, 74AHC series, 2V-5.5V supply, 8mA output, -40°C to 125°C, SOIC-16.
