Encoders, Decoders, Multiplexers & Demultiplexers

74AC138MTCX Description

The 74AC138MTCX from onsemi is a high-performance 1-of-8 decoder/demultiplexer IC designed for surface-mount applications. Part of the 74AC series, it operates over a wide voltage range (2V to 6V), making it suitable for mixed-voltage systems. This single-supply device features 3-to-8 line decoding, enabling efficient signal routing and address decoding in digital circuits. Packaged in a 16-pin TSSOP with tape-and-reel (TR) delivery, it is optimized for automated assembly processes. With 24mA output drive capability (both high and low), it ensures robust signal integrity in demanding environments. Compliant with ROHS3 and REACH standards, it meets modern environmental and safety requirements.
