ISL43110IB

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43110IB is a single-channel, Single-Pole Single-Throw (SPST) normally open analog switch manufactured by Intersil. It operates on a single supply voltage ranging from 2.4V to 12V and is housed in an 8-SOIC surface-mount package. Key electrical parameters include a maximum on-resistance of 10 ohms, with turn-on and turn-off times of 80ns and 50ns respectively. The device exhibits low leakage current, with a maximum off-state leakage of 1nA and charge injection of 8pC. Channel capacitance is specified at 15pF for both CS(off) and CD(off). It supports an operating temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized channels due to the part's obsolete status. Confirm RoHS compliance requirements as the specific listing indicates non-compliance. Ensure the 8-SOIC package dimensions match the target PCB footprint. Validate that the single-supply voltage range aligns with the system design constraints before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPST switch with low on-resistance is required for single-supply operation between 2.4V and 12V. Consider alternatives if dual-supply operation or lower charge injection is necessary. Verify that the 80ns turn-on time meets the system's timing requirements. Ensure the 8-SOIC package is suitable for the available board space and assembly capabilities.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43110IB belongs to the Intersil ISL4311x family of low-voltage, dual-supply SPST analog switches. This family includes variants like the ISL43112 and ISL43113, which offer similar performance characteristics but may differ in packaging or specific electrical tolerances. The series is designed for applications requiring low power consumption and fast switching in portable devices.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements should be verified against official Renesas/Intersil cross-reference lists or engineering change notices.
