The SN74LS138D is a 3-to-8 line decoder/demultiplexer from Texas Instruments. It has a single 1 x 3:8 circuit configuration with one independent circuit. The device operates from a single 4.75V to 5.25V supply and draws 400µA typical supply current (8mA maximum). It is designed for an operating temperature range of 0°C to 70°C. The part is housed in a 16-pin SOIC package suitable for surface mount applications.
As a member of the 74LS logic family, the SN74LS138D provides low-power Schottky performance. The 3-to-8 decoder accepts three binary inputs and provides eight mutually exclusive active-low outputs. It includes three enable inputs, two active-low and one active-high, which allow easy cascading for larger decoder arrays.
Typical applications include memory address decoding, data routing, and signal demultiplexing. The device is compatible with standard LS TTL logic levels and can be used in various digital systems requiring binary decoding or demultiplexing functions.
