SN74ACT238BQBR TI Decoder/Demux | 16-WQFN (2.5x3.5) | 3-to-8, 4.5V-5.5V

Product Overview

The SN74ACT238BQBR is a high-performance 3-to-8 line decoder/demultiplexer from Texas Instruments, designed for 5V logic systems. It features three binary select inputs (A, B, C) and an enable input (G). When enabled, the device decodes the binary input to one of eight active-low outputs. The device is fabricated using advanced CMOS technology, providing low power consumption and high noise immunity. It is available in a compact 16-WQFN (2.5x3.5mm) package, ideal for space-constrained applications.
