74HC138 IC - 3-to-8 line Decoder/Demultiplexer IC 74HC138

Product Overview The Texas Instruments 74HC138 is a High-Speed CMOS Logic 3- to 8-Line Decoder/Demultiplexer designed for high-performance memory-decoding or data-routing applications. It utilizes advanced silicon-gate CMOS technology to achieve high-speed operation, featuring a typical propagation delay of 13 ns. This device decodes three binary select inputs to choose one of eight mutually exclusive, active-low outputs. It incorporates three enable inputs (one active-high and two active-low) to significantly simplify cascading and data demultiplexing processes without the need for external gates.
