Texas Instruments SN74HCT138DE4 is a high-speed CMOS 1-of-8 decoder/demultiplexer. This component features three binary select inputs (A, B, C) and eight mutually exclusive outputs. Address inputs are decoded to activate one of the eight outputs. The SN74HCT138DE4 includes three enable inputs: two active-low (\(\overline{G1}\), \(\overline{G2A}\), \(\overline{G2B}\)) and one active-high (G3). These enable inputs provide further control over the device's operation, allowing for cascading of multiple decoders and implementing complex address decoding schemes. The device operates from a single supply voltage of 4.5V to 5.5V and is housed in a 16-SOIC package suitable for surface mounting. Typical applications include address decoding, memory selection, and data routing in digital systems. The operating temperature range is -40°C to 85°C.
