SN74LS138NS TI Decoder/Demultiplexer | 3-to-8 Line | Active Low Output

Product Overview

The SN74LS138NS 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 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 an SOP-16 package, it is ideal for space-constrained designs.
