ISL43681IRZ-T is a device from a family of high-performance, low-power, quad (4-channel) Analog Switches, Multiplexers, and Demultiplexers. This device is an ideal choice for applications requiring an on/off electrical switch in order to isolate, select, or switch multiple signals. This device is an economical, space-saving solution for multiplexing, demultiplexing, or signal isolation.

At the heart of the ISL43681IRZ-T device is a quad CMOS transfer switch. The device features on-resistance (RON) of 3.1 Ω max at 2.5 V, 5 V and 3.3 V, low CMOS leakage current, low-bounce switching, and low-charge injection specifications. The device offers a wide supply voltage range of 1.8 V to 5.5 V, a switching frequency up to 10 MHz, and a three-state logic output.

The device can also be operated as a 4:1 multiplexer/demultiplexer, allowing two independent signals to be selected with a single enable signal. The device is controlled by high/low logic inputs, making it easy to interface with a variety of systems and platforms.

The ISL43681IRZ-T is ideal for use in portable electronics and a variety of other applications. These include cellular phones, PDAs, PCs, digital cameras, camcorders, portable music and video players, navigation systems, and many other products. The device is also well suited for signal routing, signal muxing/demuxing, data acquisition, signal conditioning and signal isolation.

In signal routing applications, the ISL43681IRZ-T provides an excellent way to switch or share signal paths between various devices. In multiplexer/demultiplexer applications, the device can be used to select two independent signals with one enable signal. Data acquisition and signal conditioning applications benefit from the excellent signal isolation and low charge injection characteristics of the device. The device is also ideal for signal isolation applications, providing low leakage current and excellent repeatability.

The ISL43681IRZ-T device works on the same principle as other analog switches, multiplexers, and demultiplexers. It consists of an array of Field Effect Transistors (FETs) which act as electrical switches when they are turned on or off. The control signal is used to switch the FETs, allowing the signals to be routed. With the addition of a control logic circuit, the device can be used as a multiplexer or a demultiplexer.

In conclusion, the ISL43681IRZ-T is an ideal choice for low-power, high-performance, wide-supply-voltage applications. Its low RON, low leakage, low-bounce switching, and low-charge-injection characteristics make it perfect for signal routing, multiplexing/demultiplexing, data acquisition, signal conditioning, and signal isolation applications.
