ISL43141IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43141IRZ-T is a quad single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics Corporation. It integrates four independent channels within a compact 16-VFQFN package with exposed pad dimensions of 3x3 mm. The device operates on a single supply voltage ranging from 2.7V to 12V or dual supplies of ±2.6V to ±6V. Key electrical specifications include a maximum on-resistance of 65 ohms and a channel-to-channel matching of 2 ohms. Switching times are specified at a maximum of 80ns for turn-on and 30ns for turn-off. The component supports an operating temperature range of -40°C to +85°C and features low charge injection of 1pC, off-state leakage current of 1nA, and a crosstalk performance of -90dB at 100kHz.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation carefully during procurement as it dictates the packaging format. The base part number indicates standard tube packaging, while the IRZ-T suffix typically denotes tape and reel configuration. Confirm availability status directly with authorized distributors since discontinuation notices may affect long-term supply chains. Ensure the ordering quantity aligns with the required reel size if the tape and reel variant is selected for automated assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required within a limited board area. The 65-ohm on-resistance and 2-ohm matching make it suitable for precision analog signals where channel uniformity is critical. Verify that the 2.7V minimum supply voltage meets the system power constraints. Consider the 16-pin QFN footprint for PCB layout compatibility and thermal dissipation requirements through the exposed pad.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43141 family of analog switches from Renesas Electronics. It shares functional similarities with other members like the ISL43141IRZ but differs primarily in packaging and shipping format. The family is designed for general-purpose analog signal switching applications requiring low distortion and high bandwidth. It complements Renesas's broader portfolio of interface and signal chain components.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly documented substitutes include the ADG1212YCPZ-500RL7 from Analog Devices Inc. This alternative offers similar quad SPST functionality. Verify pinout compatibility and electrical parameter alignment before substitution. Check for any differences in package dimensions or thermal characteristics that might impact the existing PCB design.
