ISL43L711IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L711IR is a dual single-pole single-throw normally-closed analog switch manufactured by Renesas Electronics Corporation. It operates from a single supply voltage ranging from 1.65V to 3.6V and features an on-resistance of 250 milliohms maximum. The device provides two independent channels with a channel-to-channel matching of 5 milliohms. Switching times are limited to 25 nanoseconds for both turn-on and turn-off transitions. Charge injection is specified at -125 picocoulombs, while off-state leakage current remains below 3 nanoamperes. Crosstalk measures -94 decibels at 100 kilohertz. The component utilizes an 8-TDFN package measuring 3x3 millimeters and supports an operating temperature range from -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance requirements as the specific listing indicates non-compliance. Validate package markings against official datasheet specifications to prevent counterfeit substitution. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to reflow soldering processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits that require normally-closed signal paths under low-voltage constraints. The 250 milliohm on-resistance suits applications demanding high linearity and low power dissipation. Verify that the 1.65V minimum supply aligns with system power rails. Consider the 8-TDFN thermal performance if operating near the upper temperature limit.
