SN74LS138NSR TI Decoder/Demultiplexer | 16-SO | 3-to-8 Line, Active Low Output

Product Overview

The SN74LS138NSR is a 3-to-8 line decoder/demultiplexer from Texas Instruments, designed for high-performance memory decoding and data routing applications. 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 12 ns and low power consumption of 32 mW. Housed in a 16-pin SOIC package, it is ideal for space-constrained designs.
