CD74HC138EG4 is a 3-to-8 line converter circuit with decoders and multiplexers included. It is an IC digital logic gate that consists of three separate logic gates: the decoder, the multiplexer, and the gate. The design ensures that only one gate is activated at any given time. These components are used in a variety of electronic systems to transfer signals from one line to multiple lines with both a high voltage and low voltage output.

The application field of a CD74HC138EG4 is in the industrial automation field. It is used to control different electrical pulses with different voltages and currents. The flexibility of the multiplexer allows the user to establish multiple lines to the same voltage levels. This allows the user to reduce the amount of wiring in their circuit. The decoder is used to take these electrical signals and convert them from one voltage level to another. The gate is used to drive current through the lines and thus allow circuits to be switched on and off.

The working principle of the CD74HC138EG4 is to provide signals from one line to multiple lines. It can take in one 3-bit digital signal, then decode, multiplex, and gate the signal into 8 different digital lines. All of the digital lines can be wired to multiple different switches and inserted into various circuits. The functionality of the multiplexer and decoder allow for the flexibility of different types of current passing through each line. This allows the different signals to be decoded into lower voltages, and the input signal can be read.

When the CD74HC138EG4 is not in use, the control inputs can be set to a logic low. This will result in all the output lines going to a logic low. This can be advantageous when wiring to multiple switches and electronic components in a system. By having the control inputs set to a logic low, one can be sure that the proper level of current is running through each line in the system.

In conclusion, the CD74HC138EG4 is a digital logic gate that consists of a decoder, a multiplexer, and a gate. It is used in the industrial automation field to control different electrical pulses with different voltages and currents. The decoder and multiplexer allow for flexibility of the current through each line. The gate is used to switch current on and off as requested. Its purpose is to provide signals from one line to multiple lines and is an effective tool in systems that require multiple inputs and outputs.
