DM74S138N 3-To-8 Decoder For Chip Select Logic

DM74S138N is used to turn three address or control lines into one-of-eight select outputs, a common need in memory maps and peripheral enables. It reduces glue logic and helps keep decode trees readable during debug. DM74S138N is designed for high-performance decoding and demultiplexing, aimed at short propagation delay in timing-sensitive systems. Operating supply voltage is specified at 4.75 V to 5.25 V, which suits typical 5 V digital rails. With 3 inputs and 8 outputs, DM74S138N fits cleanly into bank select and device enable jobs without extra inversion stages. Keep enable pins driven from defined logic levels to avoid unintended selects during power-up. Request a quote for DM74S138N.
