Texas Instruments SN74ALS138ADG4, a high-speed TTL decoder/demultiplexer from the 74ALS series, functions as a 1-to-8 line decoder. This device features a single 1-of-8 decoding capability, accepting three binary select inputs (A, B, C) and providing eight mutually exclusive outputs. It includes enable inputs for cascading or for use as a 1-of-8 demultiplexer. The SN74ALS138ADG4 is housed in a 16-pin SOIC package designed for surface mounting. Operating from a single 4.5V to 5.5V supply, it offers typical low-power Schottky performance. This component is widely utilized in digital logic systems for address decoding, data routing, and memory selection applications across industrial and consumer electronics. The output current capabilities are 400µA high and 8mA low.
