The ISL43143IV-T is an integrated two-channel multiplexer designed for the analog multiplexing applications. It is an ideal choice for high performance signal switching systems, as well as high speed multiplexer/demultiplexer applications. The device features two channels with low RON (-90dB and -89dB at 25°C, respectively) and low off-channel leakage (0.1nA max). It is also compatible with wide range voltage supply levels which allow the use of lower supply levels, resulting in reduced power consumption.

The ISL43143IV-T is a monolithic, multi-channel low-Ron, low-leakage, analog switch and multiplexer/demultiplexer offering two digital control channels. The channels operate independently of each other, with each channel containing a digital control input. The device can be used in either single-ended or differential mode, depending on the application requirements. It has built-in protection diodes for ESD protection, resistive-mode transient suppression (the diode impedance reduces when transient signals occur), and EMI attenuation. The output drive is free of displacement, so no additional external components are required to generate the analog signals.

The ISL43143IV-T is useful in a variety of applications such as signal switching, signal routing, multiplexing, and demultiplexing. It is widely used in audio and video switching and routing, telecommunications, industrial and process control, test and measurement, video converters, and data acquisition. The device can also be used in a variety of power converters, amplifiers, and power supply applications.

The operation of the ISL43143IV-T is based on a differential pair MOSFET structure integrated with a clock driver and digital control logic. The clock input is applied to the clock driver which generates a high and low voltage corresponding to the rising and falling edges of the clock input. These two voltages are then applied to the two MOSFET gates, resulting in the desired switching action.

The ISL43143IV-T also has a wide operating temperature range of -40°C to 85°C, making it suitable for industrial and automotive applications. The device also has a low on-resistance, low power consumption, and a wide voltage range.

In summary, the ISL43143IV-T is an ideal choice for analog multiplexing applications in audio and video switching and routing, telecommunications, industrial and process control, test and measurement, video converters, and data acquisition. The device offers low channel-to-channel leakage, low on-resistance, and wide operating temperature range, making it ideal for high performance signal switching systems. Additionally, its built-in protection diodes and resistive-mode transient suppression make it suitable for use in a variety of power converters, amplifiers and power supply applications.
