ISL43L410IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L410IRZ-T is a low ON-resistance, low voltage, bidirectional, double-pole/double-throw (DPDT) analog switch designed for single +1.65V to +3.6V supply operation. It features an inhibit pin to simultaneously open all signal paths and is equipped with two normally open and two normally closed switches. The device offers ultra-low on-resistance of 0.25Ω at +3.0V and 0.4Ω at +1.8V, with fast switching speeds of tON = 12ns and tOFF = 5ns at +3.0V. It provides guaranteed break-before-make timing and is available in 10-lead thin DFN and MSOP packages.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel availability. Ensure the selected variant matches the required thermal performance and moisture sensitivity level for the intended manufacturing process. Confirm RoHS compliance status if lead-free processing is mandated by the assembly specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when board space is limited and low signal distortion is critical. Verify that the system supply voltage remains within the 1.65V to 3.6V range to maintain specified on-resistance and switching speed parameters. Consider the 1.8V logic compatibility if interfacing directly with low-voltage digital controllers without additional level shifting.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the verified documentation. Evaluate alternative DPDT analog switches based on matching supply voltage ranges, on-resistance values, and package dimensions to ensure mechanical and electrical compatibility.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum operating supply voltage for the ISL43L410?

The maximum recommended operating supply voltage is +3.6V, though the absolute maximum rating allows up to +4.7V.

How does the INH pin function?

Connecting the INH pin to V+ turns all switches off simultaneously, while connecting it to GND enables normal operation.

Is the device compatible with 1.8V logic levels?

Yes, the digital logic input is 1.8V logic-compatible when using a single +3V supply.
