ISL43L420IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L420IRZ-T is a dual-channel, single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It features normally-open channels with a maximum on-resistance of 15 ohms and a channel-to-channel matching of 0.05 ohms. The device operates on a single supply voltage ranging from 2.7V to 5.5V or a split supply of ±2.7V to ±5.5V. Key electrical parameters include a maximum on-time and off-time of 60ns, an off-isolation of -80dB at 1MHz, and a leakage current of 1nA. It is housed in an 8-TDFN package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST configuration providing independent signal routing for two channels within a compact footprint.
• Low on-resistance of 15 ohms ensures minimal signal attenuation and power loss during conduction.
• High off-isolation performance maintains signal integrity by effectively blocking unwanted crosstalk between channels.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in portable battery-powered instrumentation
• Data acquisition systems requiring low distortion
• Audio switching applications demanding high linearity

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IRZ-T' against official Renesas documentation to confirm tape-and-reel packaging and RoHS compliance status. Confirm end-of-life or obsolescence status through authorized distributors prior to procurement planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual-channel isolation is required with low on-resistance. Ensure the system voltage falls within the 2.7V to 5.5V single-supply range. Verify that the 60ns switching speed meets the application's timing requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43L4xx series of analog switches. It shares functional similarities with other members like the ISL43L120 but differs in on-resistance specifications and package options. It serves as a solution for multi-channel signal management in space-constrained designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible alternatives such as the ISL43L420 without the tape-and-reel suffix if bulk packaging is acceptable. Verify electrical parameter equivalence for on-resistance and switching times before substitution.
