ISL43144IRZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43144IRZ is a quad single-pole single-throw normally open analog switch manufactured by Renesas Electronics Corporation. It integrates four independent 1:1 switching circuits within a compact 16-VQFN package featuring an exposed thermal pad. The device supports dual power supplies ranging from ±2.6V to 6V or a single supply from 2.7V to 12V. Key electrical specifications include a maximum on-resistance of 25 ohms and a channel-to-channel matching of 500 milliohms. Switching performance is characterized by a maximum turn-on time of 65ns and a turn-off time of 50ns, with low charge injection of 5pC maximum.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors as the part is discontinued. Confirm RoHS compliance status, as specific variants may not meet current environmental regulations. Validate package dimensions against the 16-QFN(4x4) specification to ensure mechanical compatibility during replacement planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high channel matching are required for multi-channel signal processing. Ensure the operating voltage range aligns with the 2.7V to 12V single supply or ±2.6V to 6V dual supply limits. Consider the 16-VQFN package constraints for thermal management and PCB layout requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ISL43144 series of analog switches, designed for general-purpose signal switching applications. It shares functional similarities with other quad SPST switches but is distinguished by its specific 25-ohm on-resistance and 16-pin QFN footprint. The series targets applications requiring reliable signal integrity across multiple channels.
