The surface-mount package suits automated pick-and-place assembly and reflow soldering, with the tape-and-reel option enabling volume production without reel changeovers.","metaTitle":"SN74HC139DT 74HC Decoder/Demux, 1x2:4, 16-SOIC","metaDescription":"Texas Instruments SN74HC139DT dual 1-of-4 decoder/demultiplexer. 2V-6V supply, -40°C to 85°C, 16-SOIC.
