ISL43L840IVZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L840IVZ is a precision, bidirectional analog switch configured as a dual 4-channel multiplexer/demultiplexer. It features two independent SP4T circuits in a 16-TSSOP package. Key electrical parameters include a maximum on-resistance of 750 milliohms and channel-to-channel matching of 120 milliohms. The device operates from a single supply voltage range of 1.6V to 3.6V. Additional specifications include a charge injection of -96pC, off-state leakage current of 4nA maximum, and crosstalk of -100dB at 100kHz.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm RoHS compliance status and lead-free markings on the physical package. Check for recent Product Change Notices regarding assembly sites or material updates. Ensure storage conditions meet moisture sensitivity level requirements before soldering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4:1 switching is required with low on-resistance. Verify that the 1.6V to 3.6V single supply range matches the system power architecture. Consider the 16-TSSOP package dimensions for PCB layout constraints. Evaluate the -96pC charge injection against signal integrity requirements for high-precision applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43L840 belongs to the Intersil precision analog switch family, now manufactured by Renesas Electronics Corporation. This series focuses on low-distortion switching for sensitive analog signals. The IVZ suffix typically indicates a specific tape and reel packaging option or environmental compliance variant within the standard ISL43L840 product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check datasheets for pin-compatible alternatives within the ISL43xx series. Verify that substitute parts maintain the 750mOhm on-resistance and 1.6V minimum operating voltage. Confirm package compatibility with existing footprints.
