ISL43110IB-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43110IB-T is a single-channel, Single-Pole Single-Throw (SPST) normally open analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 2.4V to 12V and is housed in an 8-SOIC surface-mount package. The device features a maximum on-resistance of 10 ohms, with turn-on and turn-off times specified at 80ns and 50ns respectively. Key electrical characteristics include a charge injection of 8pC, off-state leakage current of 1nA maximum, and channel capacitance of 15pF. It supports a continuous DC switch current of 20mA and functions within an ambient temperature range of -40°C to +85°C.

• Operates on a single supply voltage from 2.4V to 12V

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-powered handheld and portable equipment
• Cellular phones and mobile communication devices
• Laptops, PDAs, and notebook computers
• Test equipment and spectrum analyzers
• Medical instrumentation such as ultrasound and ECG systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as historical Intersil data may vary. Check for end-of-life notifications given the component's age. Ensure the 8-SOIC footprint matches the target PCB design. Validate that the 10-ohm on-resistance meets system requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for low-voltage single-supply applications requiring fast switching. Compare against the ISL43111 series if normally closed operation is needed instead of normally open. Consider the ISL43113 family for dual-supply requirements up to ±6V. Evaluate power consumption needs as the quiescent current is approximately 1µA. Ensure the 20mA switch current rating exceeds the maximum load current.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43110 belongs to the Intersil ISL4311x family of low-voltage, high-performance analog switches. This family includes variants like the ISL43111 (normally closed) and ISL43112/ISL43113 (dual supply). The components are designed for battery-operated equipment due to low power consumption and sub-nanoamp leakage currents. They feature CMOS logic compatibility and break-before-make timing.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ISL43111IB-T is a functional substitute offering normally closed operation with identical electrical specifications and packaging. Verify pinout compatibility before substitution. Other members of the ISL4311x family may require different supply voltages.
