ISL43111IBZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43111IBZ is a single-channel, Single-Pole Single-Throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 2.4 V to 12 V and is housed in an SOIC-8 surface-mount package. The device features a maximum on-resistance of 10 Ohms and supports a DC switch current of 20 mA. Electrical performance includes a maximum turn-on time of 80 ns and a maximum turn-off time of 50 ns. The component functions within a temperature range of -40°C to +85°C and draws a maximum supply current of 1 µA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IBZ' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Confirm availability as the product lifecycle status may be discontinued or limited. Ensure the SOIC-8 package dimensions match the target PCB footprint before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a low-voltage, single-channel analog switch is required with minimal on-resistance variation. Verify that the 12 V maximum supply voltage meets system requirements. Consider the 10 Ohm on-resistance limit for signal integrity applications. Check if the SOIC-8 package is suitable for the assembly process compared to alternative SOT-23 packages in the same series.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL4311x family of low-voltage, dual-supply, high-performance analog switches. The family includes variants such as the ISL43112 (Normally Open) and ISL43113 (Normally Closed). These devices are designed for portable applications requiring fast switching speeds and low leakage currents.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct substitutes like the ISL43112IBZ or ISL43113IBZ if different contact states are needed. Verify cross-reference data sheets for equivalent parts from other manufacturers offering similar SPST specifications in SOIC-8 packages.
