The CD74HC138MG4 is a 3-to-8 line decoder/demultiplexer device with three enable inputs and an active-low output enable. It is designed to be used with an enable, which could be an enable of either the input or the output of a data line. It has been designed to be a major component in digital logic circuits, especially in applications with multiple data and enable lines. The CD74HC138MG4 is also specified for use in high-speed automated test systems as well as in commercial, industrial and automotive electrical and electronic applications. It uses three inputs (A0, A1, A2) and an enable line E to generate up to 8 active-low outputs (Y0–Y7). The combination of inputs determines which particular output is active. The decoder provides up to 8 independent inputs, depending on the number of active-low outputs. The CD74HC138MG4 is compatible with most logic families, making it a very useful device for applications such as interfacing, logic gates/circuits, microprocessor applications, and logic/analog switches. In logic applications, the device is often used to translate command level logic into micro-controller level logic, simplify the decoding of data signals and increase the available I/O (input/output) options. The working principle of CD74HC13MG4 is designed to be used with an enable, which could be an enable of either the input or the output of a data line. By applying one of the inputs (A0, A1, and A2) and the enable (E) the decoder will activate the corresponding output (Y0-Y7). When the number of outputs provided is less than the number of inputs, the remaining outputs will remain inactive. This can be useful in multiplexer applications, since a single line can be used to activate or deactivate multiple inputs.The CD74HC138MG4 also features an active-low output enable pin, which is used to actively disable outputs. This function is helpful in allowing the multiplexing of data, since no output will be activated if the output enable pin is not enabled. Additionally, the output enable pin may also be used for other functions such as gating data or resetting a circuit. In summary, the CD74HC13MG4 is a highly versatile decoder/demultiplexer that can be used in a variety of digital logic and analog applications. It offers a high level of decoding/demultiplexing, by enabling the user to select from up to 8 outputs with just 3 inputs and 1 enable. The device also features an active-low output enable pin, which allows for multiplexing data and other circuit functions.
