ISL43111IHZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43111IHZ-T is a single-channel, Single-Pole Single-Throw (SPST) normally closed analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 2.4V to 12V and is housed in a 5-SOT (SC-74A/SOT-753) surface-mount package. The device features a maximum on-resistance of 10 ohms, with turn-on and turn-off times of 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 DC switch current of 20mA and functions within an ambient temperature range of -40°C to 85°C.

• Medical instrumentation such as ultrasound and ECG systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel quantity matches project requirements. Confirm that the SC-74A package dimensions align with the PCB footprint design. Check RoHS compliance status if restricted substances are mandated by regional regulations. Ensure the single-supply voltage range meets the system's power budget constraints before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog switch is required for low-voltage single-supply applications. The 10-ohm on-resistance and fast switching times make it suitable for high-frequency signal routing. Compare against the ISL43110 variant if a normally open configuration is needed instead. Consider the 5-pin SOT package size for space-constrained designs requiring surface-mount assembly.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL4311x series of low-voltage, dual-supply, SPST high-performance analog switches. The family includes variants like the ISL43110 (normally open) and ISL43113 (dual supply). These devices are designed for applications requiring low power consumption, sub-nanoamp leakage currents, and break-before-make operation. They are CMOS logic compatible and offer excellent on-resistance flatness.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ISL43110IHZ-T is a direct functional substitute if a Normally Open (NO) configuration is acceptable instead of Normally Closed (NC). Other members of the ISL4311x family may serve as alternatives depending on the required switch state and supply voltage specifications.
