Introduction
The ISL43140IB is an analog switch, multiplexer, and demultiplexer manufactured by Intersil Corporation. It is designed to operate in both single-supply and dual-supply operation, and is capable of switching both AC and DC signals. The device is suitable for use in automotive, consumer, and industrial applications, and is packaged in a small 8-pin SOIC package.Features
The ISL43140IB offers several features that make it suitable for a wide variety of analog applications. It is capable of switching both single and dual supply voltages with a low on resistance of 0.4Ω, and is rated for operation over a wide -20°C to +85°C temperature range. Additionally, the device offers low input current of 0.1 µA, and fast switching times of 10 ns. The device also has a low power consumption of 5.6 mW in single supply operation, and a high input impedance of >100GΩ to ensure that the device does not load the signal source. It is also designed to be relatively resistant to ESD, and is rated for ±2000V of sustained ESD immunity.Applications
The ISL43140IB is designed for use in a wide range of automotive, consumer, and industrial applications. In automotive applications, the device can be used for audio switching, instrument panel layout switches, and HVAC control switches. In consumer applications, the device can be used for LCD backlighting control, audio switching, and speech recognition circuit switching. In industrial applications, the device can be used for pressure sensor switching, multiplexer switching, and relay control.Working Principle
The ISL43140IB operates by switching between a signal source and signal destination. When the device is not activated, the signal source is connected to the signal destination via the device’s internal resistor, the on-resistance of which is typically 0.4Ω.When the device is activated, an internal multiplexer switches the signal source and signal destination, allowing the signal to pass through the device. The signal is then routed through the device’s internal resistance, before being switched back to the signal destination. This allows the signal to be passed through the device without loss.The device is activated by applying a logic control signal to the corresponding logic control Pin. This control signal is typically generated by an external controller such as an MCU or PLC, and is used to switch the signal between the signal source and signal destination.Conclusion
The ISL43140IB is an analog switch, multiplexer, and demultiplexer that is well suited for automotive, consumer, and industrial applications. It is capable of switching AC and DC signals between single and dual supply voltages with a low on resistance of 0.4Ω, and is rated for operation over a wide -20°C to +85°C temperature range. It is also capable of switching signals with a high input impedance of >100GΩ and low input current of 0.1 µA, and is rated for ±2000V sustained ESD immunity.The specific data is subject to PDF, and the above content is for reference
