ISL43840IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43840IR is a dual single-pole double-throw (SPDT) analog switch manufactured by Renesas Electronics Corporation. It features two independent channels, each switching between two inputs to one output, housed in a 16-pin VFQFN package measuring 4x4 mm. The device operates with a single supply voltage ranging from 2.7V to 12V or dual supplies of ±2V to ±6V. Key electrical specifications include a maximum on-resistance of 50 ohms and a channel-to-channel matching of 1.3 ohms. Charge injection is limited to 0.3pC, while leakage current remains at a maximum of 100pA. The component supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Wide single and dual power supply compatibility for flexible system integration

Analog Switches, Multiplexers, Demultiplexers Applications

Signal routing in test and measurement equipment
Data acquisition systems requiring low distortion switching
Communication infrastructure for line termination control

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IR' against the manufacturer's latest documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as historical data indicates potential non-compliance for this series. Check for active production status or last-time-buy notifications before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ISL43840IR when dual SPDT functionality is required rather than quad configurations. Ensure the 50-ohm on-resistance meets the signal integrity requirements of the application. Verify that the 16-pin QFN package fits the available PCB real estate compared to the 20-pin variants found in similar families.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ISL4384x family of high-speed analog switches. It shares architectural similarities with the ISL43841 but differs in switching topology, offering SPDT instead of SP4T configurations. The part is designed for applications demanding low crosstalk and fast switching speeds in portable and industrial electronics.
