Logic-signal switches, multiplexers, and decoders enable efficient data transmission by switching or altering information entering or leaving an integrated circuit (IC). The 72V70840DA Multiplexer decoder is an 8-channel multiplexer/decoder IC that is the ideal solution for multiplexing and demultiplexing digital and analog signals. Aimed at applications such as digital storage, test and measurement, and consumer electronics, the 72V70840DA supports serial data protocol and can withstand high voltage levels. In this article, we\'ll look at the application fields and working principle of the 72V70840DA.

Application Fields

The 72V70840DA can be used for multiplexing and demultiplexing data in a variety of applications. These include medical instruments, automotive infotainment systems, industrial control systems, telecommunications, process automation and control systems, and consumer electronics.

The 72V70840DA offers flexible input and output interfaces that meet the needs of these applications, as well as offering high-speed data transfer and a wide range of test and measurement capabilities. It also has a wide temperature range and low power consumption, making it suitable for many environmental conditions.

Its built-in array of signals transceivers allows it to operate in both receive and transmit modes, making it suitable for a variety of applications that require both high-speed signal processing and data transmission.

Working Principle

The 72V70840DA is a type of multiplexer/decoder IC that can connect multiplexing and demultiplexing digital and analog signals. It consists of eight independent channels, each having a multiplexer control and a decode logic for buffering and routing signals. The decode logic is responsible for selecting one of the eight channels to route the signal, as well as for expressing each of the eight channels as two binary-coded decimal digits.

The multiplexer control consists of two logic signals and one enable signal. The two logic signals, namely A and B, select which of the eight channels will be active in the case of a multiplexer. When both A and B are set to a logic “1”, the multiplexer control enables the decode logic, thus allowing the signal to be routed through the selected channel. When either A or B is set to a logic “0”, the signal is routed according to the binary-coded decimal digits.

The 72V70840DA also features a built-in bias voltage and delay signal that allow it to be used in high-voltage applications. The delay signal, which connects to the inputs of the multiplexer, can delay the signal by several microseconds, allowing more tolerance to the data transmission.

Lastly, the 72V70840DA has a host of other features such as an on-board memory array, a wake-up signal, and an integrated comparator, as well as ESD protection, over-voltage protection, and thermal protection.

Conclusion

The 72V70840DA is a multiplexer/decoder IC with an array of features that make it suitable for a variety of applications that require multiplexing and demultiplexing digital and analog signals. It has a wide temperature range and low power consumption, as well as adjustable delay and bias voltages. It also features an on-board memory array, a wake-up signal, and integrated comparator, as well as ESD protection, over-voltage protection and thermal protection.
