ISL43741IR

Analog Switches, Multiplexers, Demultiplexers Overview

The Intersil ISL43741IR is a low-voltage, single and dual supply, high-performance quad SPST analog switch. It operates from a single +2V to +12V supply or ±2V to ±6V supplies. Key electrical parameters include an ON resistance (RON) of 50Ω maximum, RON matching between channels of 2Ω, charge injection of 5pC maximum, and power consumption under 1μW. Leakage current is specified at 5nA maximum at 85°C. Switching speeds are characterized by tON of 30ns and tOFF of 18ns. The device utilizes a 3mm x 3mm QFN package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Quad single-pole/single-throw (SPST) configuration with four separately controlled switches
Low leakage currents and fast switching speeds for signal fidelity
Pin compatible with DG411/DG412/DG413 devices

Analog Switches, Multiplexers, Demultiplexers Applications

Battery powered equipment requiring low power consumption
Signal routing in data acquisition systems
Audio and video signal switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IR' against official Intersil documentation to confirm tape-and-reel packaging and temperature range specifications. Ensure compatibility with existing board layouts due to the QFN footprint. Cross-reference pinouts with legacy equivalents like the DG411 if replacing older designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST topology is required with low voltage operation. Consider the 50Ω RON and 30ns/18ns switching times for bandwidth requirements. The QFN package is suitable for space-constrained designs. Verify that the ±2V to ±6V or +2V to +12V supply rails match the system architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43741 belongs to the ISL4314x series of CMOS precision analog switches. While the ISL43140 features normally closed switches and the ISL43142 offers mixed NO/NC configurations, the ISL43741 specifically provides four normally open switches. This series targets applications demanding low power and high signal integrity.
