ISL43L710IUZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L710IUZ is a dual-channel, single-pole/single-throw (SPST) analog switch from the ISL43L71x family. It operates on a single supply voltage ranging from +1.65V to +3.6V and features two normally open switches. The device provides an ultra-low on-resistance of 0.16Ω at 3V and 0.26Ω at 1.8V, with channel-to-channel matching of 0.005Ω. Switching times are 13ns/13ns at 3V and 30ns/25ns at 1.8V. It offers low power consumption, high off-isolation, and crosstalk rejection of -94dB at 100kHz. The component is housed in an 8-lead MSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify RoHS compliance status as the datasheet indicates Pb-free availability but does not explicitly confirm the specific suffix Z status for all batches without checking the ordering information table. Confirm the manufacturer origin, noting the transition from Intersil to Renesas Electronics Corporation. Ensure the component matches the 8-lead MSOP physical dimensions before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when designing low-voltage systems requiring bidirectional SPST switching with minimal resistance variation. The ISL43L710 specifically suits applications needing two normally open paths. Consider the 1.8V CMOS compatibility for direct interface with microcontrollers. Evaluate thermal constraints, as the MSOP package has a thermal resistance of 190°C/W.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ISL43L71x series, which includes the ISL43L711 (two NC switches) and ISL43L712 (one NO and one NC switch). The ISL43L710 is distinguished by its dual normally open configuration. The family is designed for space-constrained portable devices, offering small form factor packages like TDFN and MSOP to alleviate board space limitations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the ISL43L210 as the recommended replacement part for new designs. Verify pinout compatibility and electrical specifications against the original requirements before substitution.
