Logic - Signal Switches, Multiplexers, Decoders are a special class of microchips that are used to manipulate, encode, and decode data in a digital form. 74VHC138SJ is a high-performance chip that belongs to this class and offers a range of versatile applications.

When it comes to feature sets, 74VHC138SJ is equipped with three select inputs (A0, A1, and A2), eight data inputs (B0 to B7), three active low enable inputs (E1, E2, and E0), an output enable (OE) input, and thirteen active high outputs (Y0 to Y12). This combination makes it an excellent chip for working with logic-level signals.

As for the applications themselves, 74VHC138SJ chips are used in a wide range of scenarios. One of the most prominent examples is for switching digital signals between multiple devices, as it can be used to select the appropriate output using its address and enable inputs. Accordingly, these chips can also be used to split a digital signal into multiple lines.

Another common scenario is to use 74VHC138SJ chips in conjunction with multiplexers. In this case, the select inputs (A0, A1, and A2) can be used to select which multiplexer channel should be activated, while the data inputs (B0 to B7) provide the data inputs needed by the multiplexers. This allows the user to create a system that can switch multiple signal sources and destinations.

Further, 74VHC138SJ chips can also be used as decoders. Here, the address inputs (A0, A1, and A2) are used to select which output should be activated, while the data inputs (B0 to B7) introduce data that needs to be decoded. Thus, 74VHC138SJ can be used to create digital encoders, which are used to convert from one signal format to another.

Last but not least, 74VHC138SJ chips are also very useful in automated systems. In particular, the active low enable inputs (E1, E2, and E0) combined with the output enable (OE) input allow for the chip to be controlled remotely and to initiate automated operations.

In summary, 74VHC138SJ chips are an excellent choice for any logic-level signal applications. They are very versatile and can act as signal switches, multiplexers, decoders, and automated systems when needed. As such, they are an indispensable part of modern digital technology.
