The NC7SZ384P5X is a logic–signal switch, multiplexer, and decoder designed for use with low-voltage portable applications and provides integrated signal decoder output for ease of use. The device comes in two- and four-channel versions, with each channel being individually selectable with just four pins from the outside. It supports single-ended inputs, and it is optimized for use with low-voltage applications such as USB or battery-powered devices.

Functionality

The NC7SZ384P5X is an IC-based logic–signal switch, multiplexer, and decoder. It acts as a signal switch between two separate circuits or as a multiplexer and decoder to reduce the number of lines needed to control multiple circuits or devices. Each of the channels has its own single-ended input, so the same logic level can be applied to multiple channels. The device provides integrated signal decoder output which allows the switching of any single-ended input to the outputs in response to the logic levels provided.

Application

The NC7SZ384P5X is designed for use in low-voltage applications and provides integrated signal decoder output for ease of use. It can be used with USB peripherals, battery-powered devices, consumer applications, as well as automotive and industrial applications. Typical applications include data multiplexer/demultiplexer, multiplexer/demultiplexer controller, signal selector and signal de-multiplexer.

Working Principle

The NC7SZ384P5X logic–signal switch, multiplexer, and decoder works using N-channel MOSFETs as switching elements and a logic input signal to control voltage switching. The input logic level is passed through the N-channel MOSFETs, which act as an electronic switch. Each MOSFET has an input and an output, and the input is controlled by the logic level. The logic level is used to determine which output will be activated and which input will be used. The output voltage is then switched to the voltage of the selected input.The N-channel MOSFETs in the NC7SZ384P5X are configured in the differential-amplifier amplifier mode, which is commonly used for signal switching, multiplexing, and decoding. The differential-amplifier mode uses two input signals and two output signals. When one input signal is low, the other is high, and the two outputs are switched accordingly. The output voltage from the selected input will be switched to the output voltage. The output voltage is then used as the value for the selected input.

Conclusion

The NC7SZ384P5X is a logic–signal switch, multiplexer, and decoder designed for low-voltage portable applications and provides integrated signal decoder output for ease of use. It is capable of switching any single-ended input to the outputs in response to the logic levels supplied. The device\'s MOSFET configuration in differential-amplifier mode gives it increased flexibility and usability in a variety of applications, including its use as a data multiplexer/demultiplexer, multiplexer/demultiplexer controller, signal selector and signal de-multiplexer.
