ISL43113IB-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43113IB-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. Key electrical parameters include an on-resistance of 15Ω, on-resistance flatness of 5Ω, and charge injection of 7pC. The device features fast switching times with turn-on at 40ns and turn-off at 25ns. Leakage currents are specified as 5nA maximum in the off state and 20nA in the on state at 85°C. It offers minimum 2000V ESD protection per Method 3015.7 and consumes 250μW power.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IB-T' against official Renesas documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with existing supply voltages and logic levels before procurement. Check for obsolescence status or lifecycle notices as Intersil products may have transitioned to Renesas manufacturing lines.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ISL43113IB-T for normally closed (NC) SPST applications requiring low voltage operation. Compare on-resistance and leakage current requirements against alternative models like the ISL43112 if normally open functionality is needed instead. Consider the SOT-23 package size constraints and verify that the 15Ω on-resistance meets the signal path loss requirements of the specific application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43113 is part of the Intersil/Renesas ISL4311x family of precision analog switches. This family includes the ISL43112 (Normally Open) and ISL43113 (Normally Closed). These devices were designed to replace older single SPST switches with improved speed and lower power consumption, targeting next-generation portable and battery-powered designs.
