The ISL43142IVZ is an advanced, low power, low noise, high performance single-supply CMOS analog switch and logical gate. It is an advanced dual-channel differential multiplexer/demultiplexer (MUX/DEMUX) that is capable of providing very low power consumption (15μA maximum) while still offering excellent performance. The ISL43142IVZ also has a robust selection of logical inputs, making it perfect for operation in a variety of applications.

The ISL43142IVZ is ideal for use in many applications, such as driving analog circuits over long cable lengths, providing isolation of inputs to reduce power supply noise, and in test and measurement equipment. The device can be used in many other applications as well, such as multiplexing and demultiplexing audio input signals, and controlling the sequence of multiplexed output signals. The low-power consumption and noise immunity of the ISL43142IVZ make it ideal for low power applications such as mobile communication and portable devices.

The ISL43142IVZ is a precision device that offers excellent switching characteristics, linearity and low distortion with a typical on-resistance of less than 0.1Ω at 3.3V. The device is also specified for low harmonic distortion of 0.08% at 10V, making it suitable for audio applications such as volume control. The on-resistance flatness over the supply voltage range of the device is typically less than 0.2Ω.

The logic input ports of the ISL43142IVZ are high impedance and can accept voltages up to 24V, making them suitable for direct connection to an external voltage or a bus. The input supports both CMOS and TTL levels, providing flexibility in connecting to a wide range of logic levels. Additionally, the logic inputs can also support high-speed logic including 5V CMOS and TTL, making the device suitable for high-speed switching applications.

The differential multiplexing/demultiplexing of the ISL43142IVZ is accomplished using the A and B ports. When driven by the output Enable control, the device alternately switches the digital signal between the A and B ports, allowing data to be viewed or switched between two ports. The MUX/DEMUX ports support both differential and single-ended logic levels, making the device suitable for a wide range of applications. The differential input impedance on the ports is typically very low (less than 2Ω).

The ISL43142IVZ also has an output Enable control that is used to enable or disable the device. The output Enable has an open drain output that is used to control the MUX/DEMUX action of the device. The output Enable has an input threshold voltage of 2.4V, making it suitable for various logic levels. Additionally, the output Enable can be used to control the power-down mode of the device, allowing the device to be placed in a low power state when not in use.

The ISL43142IVZ is an ideal solution for applications requiring high performance, low power consumption, and immune to noise. This device is well-suited for use in many applications such as audio applications, switching inputs and outputs, isolating inputs, and providing signal conditioning. The ISL43142IVZ is a must-have for any engineer looking to develop high performance switching devices.
