ISL43L111IHZ-T is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Renesas Electronics Corporation. Its product description is IC SW SPST-NCX1 220MOHM SC70-5. Review the specifications below when checking this part for your BOM.
The ISL43L111IHZ-T is a single-pole/single-throw (SPST) normally-closed analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 1.1V to 4.5V and features an ultra-low typical on-resistance of 220mΩ. The device provides fast switching times with maximum turn-on and turn-off delays of 15ns and 10ns, respectively. Packaged in a compact SC-70-5 (SOT-353) surface-mount housing, it supports bidirectional signal transmission with low charge injection and leakage current characteristics suitable for precision applications.
Verify the specific suffix 'IHZ' confirms the SOT-353 package variant and tape-and-reel delivery format. Ensure the selected component matches the required normally-closed logic state and single-supply voltage range. Cross-reference the manufacturer datasheet for thermal derating guidelines and soldering profile recommendations to maintain reliability during assembly processes.
Select this component when space-constrained designs require low on-resistance and fast switching within a 1.1V to 4.5V supply range. Compare against alternatives based on package footprint compatibility and specific on-resistance tolerances. Consider the normally-closed configuration requirements versus normally-open variants available in the same product family for circuit topology alignment.
This part belongs to the ISL43L11x series of ultra-low resistance analog switches designed for low-voltage applications. It shares functional similarities with the ISL43L110 but differs in its default contact state. The series emphasizes performance in portable electronics where power efficiency and signal integrity are critical constraints.
