In a typical system it selects one memory bank, enables one peripheral chip, or routes a signal to one of eight destinations — the sort of address decoding you see on a board with multiple parallel devices. The single 3:8 configuration (one decoder section, eight outputs) fits designs that need exactly one decode tree without leftover gates. ## Temperature range and output drive Rated for -55°C to 125°C, this is the full military temperature grade — the same die that goes into defence and aerospace builds. If your board sits in an engine bay, a satellite orbit, or a downhole tool, this part keeps decoding when commercial-grade parts drift out of spec. For heavier loads you buffer the output with a transistor or a gate driver — the 5.2 mA figure tells you the fan-out ceiling to standard 74HC inputs (about 10 loads per output).","metaTitle":"CD74HC238M Texas Instruments 74HC Decoder/Demux, 1x3:8","metaDescription":"Texas Instruments CD74HC238M 74HC decoder/demultiplexer, 1 x 3:8 circuit, 2V-6V supply, -55°C to 125°C, active production, ROHS3 compliant.
