ISL43145IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43145IRZ-T is a quad single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics. It integrates four independent channels in a 16-pin QFN package with dimensions of 3x3 mm. The device features a maximum on-resistance of 20 ohms and a channel-to-channel matching of 250 milliohms. It operates from 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-time of 65ns, off-time of 50ns, charge injection of 5pC, and leakage current of 100pA. The component supports an operating temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as some variants may differ. Check for obsolescence notices since this part number series has faced discontinuation risks. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent low-resistance switches are required in a small footprint. Compare on-resistance values against other models like ISL43141 if higher resistance is acceptable for cost savings. Verify that the 20-ohm maximum on-resistance meets the signal integrity requirements of the target application circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL4314x family of analog switches from Renesas. It shares similar pinouts and functionality with variants such as ISL43141 and ISL43144 but differs in on-resistance specifications. The family is designed for general-purpose analog signal switching in industrial and consumer electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ISL43145IRZ-T is considered obsolete. Publicly confirmed substitute part numbers include ADG1212YCPZ-500RL7 from Analog Devices Inc. Verify pin compatibility and electrical parameter alignment before substitution.
