ISL43L711IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L711IR-T is a dual-channel, single-pole/single-throw (SPST) analog switch featuring normally closed contacts. It operates on a single supply voltage ranging from +1.65V to +3.6V and is housed in an 8-lead Thin Dual Flat No-Lead (TDFN) package with dimensions of 3mm x 3mm. The device provides an ultra-low on-resistance of 0.26Ω at 1.8V and 0.16Ω at 3.0V, with channel-to-channel matching of 0.005Ω. Switching times are specified at 30ns for turn-on and 25ns for turn-off at 1.8V, reducing to 13ns each at 3.0V. It exhibits low power consumption of 0.12μW and supports bidirectional signal paths.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as discontinued or obsolete before finalizing designs. Confirm that the -T suffix indicates tape and reel packaging per manufacturer guidelines. Ensure compliance with moisture sensitivity levels and handling procedures for surface mount devices during assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring differential SPST switching within a 1.65V to 3.6V range. Consider the 8-lead TDFN package for space-constrained layouts. Evaluate thermal resistance characteristics if operating near maximum temperature limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ISL43L71x family, which includes the ISL43L710 and ISL43L712 variants. These devices share similar electrical characteristics but differ in contact configuration, such as normally open or mixed NO/NC arrangements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly recommends the ISL43L210 as the recommended replacement part for new designs due to the discontinuation of the ISL43L71x series.
