The SN74LV139ADR is a dual 1-of-4 decoder/demultiplexer from TI's 74LV low-voltage logic family. Each of the two independent circuits takes a 2-bit binary address and asserts one of four active-low outputs.
The 12 mA per output pin (both high and low) drives CMOS logic inputs or a small LED indicator directly. The 16-SOIC package is a standard footprint.
Both are dual 2:4 decoders with active-low outputs, but the LV family runs on 2V to 5.5V and is CMOS, while the LS family is bipolar and runs 4.75V to 5.25V. The LV part draws lower quiescent current and is a drop-in functional replacement on 5V boards, but verify the output drive and timing against your specific design — the LS part has different switching thresholds.
