ISL43L121IU-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L121IU-T is a dual single-pole double-throw (SPDT) analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 1.65V to 3.6V. The device features a maximum on-resistance of 250 milliohms and a channel-to-channel matching of 5 milliohms. Switching times are limited to 25ns for both turn-on and turn-off. Charge injection is specified at -125pC, with off-state leakage current capped at 3nA. Crosstalk measures -94dB at 100kHz. The component is housed in an 8-MSOP package and supports an operating temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official documentation, as standard datasheets typically list the ISL43L121IU variant. Confirm RoHS compliance status, noting that the base model may not meet current regulations. Check for end-of-life notifications or product discontinuance notices from the manufacturer before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high accuracy are required for low-voltage applications. Ensure the supply voltage remains within the 1.65V to 3.6V range. Consider the 8-MSOP package dimensions for PCB layout constraints. Verify thermal requirements against the specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43L12x series of low-voltage analog switches. It shares core electrical characteristics with the ISL43L120 and ISL43L122, differing primarily in contact configuration. The series is designed for space-constrained portable electronics requiring high signal integrity.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ISL43L120IRZ offers a similar electrical profile but utilizes an 8-TDFN package and features normally-open contacts. Verify pinout compatibility and contact state requirements before substitution.
