ISL43113IB

Analog Switches, Multiplexers, Demultiplexers Overview

The Intersil ISL43113IB is a low-voltage, dual-supply Single-Pole Single-Throw (SPST) analog switch featuring Normally Closed (NC) logic. 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, rON flatness of 5Ω, and charge injection of 7pC. Leakage currents are 5nA (off) and 20nA (on) at maximum temperature. Switching times are tON: 40ns and tOFF: 25ns. The device provides minimum 2000V ESD protection per Method 3015.7 and consumes 250μW power.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IB' against official Intersil or Renesas documentation to confirm package type and temperature range specifications. Ensure compatibility with existing board layouts for SOT-23 packaging. Confirm end-of-life status if sourcing from secondary markets, as the base model may be obsolete.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ISL43113IB when a Normally Closed (NC) configuration is required for SPST switching applications. Compare against the ISL43112 if a Normally Open (NO) state is needed instead. Consider the low leakage current and fast switching speeds for battery-powered designs where power consumption and signal fidelity are critical constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43113IB belongs to the ISL4311x family of precision analog switches manufactured by Intersil, now part of Renesas. This family is designed for next-generation low-voltage designs, offering small SOT-23 packaging to alleviate board space limitations while maintaining high performance metrics suitable for portable electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers for the ISL43113IB are not available in the provided source material. Verify cross-compatibility with other NC SPST analog switches only through detailed parameter matching of resistance, leakage, and switching speeds.
