ISL8484IRZ

Interface - Analog Switches, Multiplexers, Demultiplexers

Analog switches, multiplexers, and demultiplexers are electronic components which enable a connection between two electronic devices. They can be used to route analog or digital signals, allowing for the selection of a single input and the delivery of an output to the same or multiple devices. The ISL8484IRZ is a monolithic device used in such applications.

ISL8484IRZ Application Field

The ISL8484IRZ is designed to be used in a variety of applications including communications, medical, industrial, and consumer electronics, as well as audio and broadcast equipment. It is a single-supply device that operates from a voltage range of 2.0V to 5.5V, making it ideal for portable or battery-powered systems. Additionally, it can be connected to a 3.3V supply, allowing it to interface with a variety of devices.

ISL8484IRZ Working Principle

The ISL8484IRZ is an analog switch, multiplexer, and demultiplexer device that can be used in a variety of applications. In its simplest form, it can be used as a single-pole double-throw switch, connecting a single input to any one of four single outputs. Alternatively, it can be used as a multiplexer and demultiplexer. The multiplexer enables the selection of up to four different digital inputs to be passed to a single output. The demultiplexer allows for a single input to be routed to up to four different output devices. The device can be operated in either a push-pull or open-drain configuration.

The ISL8484IRZ is designed to be easy to use, with a selectable operating mode and low on-resistance. It features an integrated termination switch, discharge switch, and a high linearity difference amplifier, which allows for both low-power and high-power applications. It is available in an 8-pin package.

Conclusion

The ISL8484IRZ analog switch, multiplexer, and demultiplexer device is a useful component for a wide range of applications. It provides a low-power solution, allowing for a variety of uses, from communications to audio. The integrated termination switch, discharge switch, and difference amplifier make for a versatile device that can be switched between push-pull or open-drain configurations. It is an ideal choice for low-power portable systems.
