74LVC139DB,112 is a dual high-speed 1-of-4 Decoder/Demultiplexer and two-line to four-line decoder/demultiplexer with common-output-enable, which is designed for use in high-speed memory decoder applications, as well as address and data distribution. It contains two independent 1-of-4 decoders with common-output-enable. Outputs are active-low.

The main application field of 74LVC139DB,112 includes storage decoders, multiplexer and decoder significance, address and data distribution, memory selection and sequencing, etc. The 74LVC139DB,112 is extensively used in most computer and electronic systems, including cell phones, tablets, computers, and other electronic devices.

The working principle of 74LVC139DB,112 is based upon the decoding of binary encoded signals. The device utilizes two active-low inputs (S1 and S2) to decode and the active-low outputs respond to binary input code combinations. It is designed for asynchronous operation and the outputs are enabled when an active-low common output enable (E) is present. If a \'low\' is applied to E, the outputs will activate depending upon the logic level at the Select inputs (S1 and S2). When E is \'high\', all outputs are deselected regardless of the logic levels of S1 and S2. The 74LVC139DB,112 is suitable for multiplexers, decoders, storage selectors, and address and data distribution.

The 74LVC139DB,112 is a dual high-speed 1-of-4 Decoder/Demultiplexer and two-line to four-line decoder/demultiplexer with common-output-enable. It operates at high-speed for fast memory decoder applications. It has two independent 1-of-4 decoders and uses the active-low inputs (S1 and S2) to decode. The output is enabled when an active-low common output enable (E) is present. The device is suitable for multiplexers, decoders, storage selectors, address and data distribution in most electronic and computer systems.
