ISL43113IH-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43113IH-T is a low-voltage, dual-supply, Single-Pole Single-Throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It operates from ±1.5V to ±6V supplies and is fully specified for ±5V and ±3.3V with 10% tolerance. The device features an ON-resistance of 15Ω with a flatness of 5Ω, charge injection of 7pC, and off-leakage current of 5nA at 85°C. Switching times are tON: 40ns and tOFF: 25ns. It provides break-before-make operation and minimum 2000V ESD protection per Method 3015.7. The component is housed in a 5-SOT package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix IH-T against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Check for end-of-life status or obsolescence notices as this component family may have been superseded. Ensure RoHS compliance matches current regulatory requirements for your region. Confirm availability through authorized distributors given potential discontinuation trends.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ISL43113IH-T when a Normally Closed (NC) SPST configuration is required for dual-supply analog switching. Compare ON-resistance and leakage specifications against single-supply alternatives if power constraints allow. Consider the SOT-23 footprint for board space limitations. Verify that the 15Ω ON-resistance meets the signal integrity requirements of the application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43113 is part of the Intersil/Renesas ISL4311x series of precision analog switches. It is the Normally Closed variant, whereas the ISL43112 is the Normally Open version. These devices were designed for next-generation low-power designs requiring small packaging and high performance. The series targets applications benefiting from sub-nanoamp leakage and fast switching speeds.
