SN74ALS138ADB TI Decoder/Demultiplexer | 16-SOIC | 3-to-8 Line, 4.5V-5.5V

Product Overview

The SN74ALS138ADB is a high-performance 3-to-8 line decoder/demultiplexer from Texas Instruments, designed for 4.5V to 5.5V operation. It features three enable inputs (two active low and one active high) to simplify cascading and system expansion. The device is fabricated using advanced Schottky-clamped TTL technology, providing a typical propagation delay of 6 ns and low power consumption of 22 mW. Housed in a 16-pin SOIC package, it is ideal for memory decoding, data routing, and control logic in industrial and telecommunications systems.
