SN74ALS155D TI Decoder/Demultiplexer | Dual 2-to-4 Line, 4.5V-5.5V

Product Overview

The SN74ALS155D is a dual 2-to-4 line decoder/demultiplexer from Texas Instruments, designed for high-performance memory decoding and data routing applications. It features two independent decoders with active-low outputs, each capable of demultiplexing a 2-bit input to 4 mutually exclusive outputs. The device operates from a 4.5V to 5.5V supply, making it suitable for 5V logic systems. With typical propagation delays of 6ns and low power consumption, it is ideal for high-speed digital systems.
