SN74ALS156DR TI Dual 2-to-4 Decoder | 16-SOIC | 4.5V-5.5V, 24mA Output

Product Overview

The SN74ALS156DR from Texas Instruments is a dual 2-line to 4-line decoder/demultiplexer designed for high-performance memory decoding and data routing applications. It features two independent decoders with active-low outputs and enable inputs, making it ideal for address decoding in microprocessor systems. The device operates from a 4.5V to 5.5V supply and offers 24mA output drive capability. Housed in a 16-pin SOIC package, it is suitable for space-constrained designs.
