ISL43L840IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L840IRZ-T is a precision, bidirectional analog switch configured as a dual 4-channel multiplexer/demultiplexer. Designed for single-supply operation from +1.6V to +3.6V, it features an ultra-low on-resistance of 0.5Ω at +3V and 0.62Ω at +1.8V. The device handles rail-to-rail analog signals with a maximum off-leakage current of 4nA at +25°C and 30nA at +85°C when supplied at +3.3V. It offers fast switching action with a transition time of 19ns at +3V and supports 1.8V CMOS logic compatibility. The component is housed in a 16-lead 3x3 QFN package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix IRZ-T against official Renesas documentation to confirm the tape-and-reel packaging format. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Check for moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring dual 4:1 multiplexing under strict low-voltage constraints. Ensure the system supply voltage remains within the 1.6V to 3.6V range. Verify that the 1.8V logic interface compatibility meets the control circuit requirements. Consider the 3x3 QFN package dimensions for PCB layout constraints.
