onsemi Signal Switches, Multiplexers, Decoders MC74ACT139NG

The MC74ACT139NG is a high-speed dual 1-of-4 decoder/demultiplexer from Quarktwin Technology Ltd. It features two independent decoders, each accepting two binary inputs and providing four mutually exclusive active-LOW outputs. The device includes an active-LOW enable input for each decoder, which can also function as a data input for demultiplexing applications. The outputs can source or sink up to 24 mA, making it suitable for various logic applications. The MC74ACT139 is TTL compatible and is available in multiple package types, including PDIP, SOIC, and TSSOP. It operates within a supply voltage range of 4.5V to 5.5V for the ACT version and is designed for a wide temperature range of -40¬8C to 85¬8C. This product is ideal for applications requiring efficient signal routing and logic function generation.
