ISL43L712IRZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L712IRZ is a dual single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation, formerly Intersil. It features two independent channels with normally open and normally closed configurations housed in an 8-TDFN package. The device operates on a single supply voltage ranging from 1.65V to 3.6V. Key electrical specifications include a maximum on-resistance of 250 milliohms and a channel-to-channel matching of 5 milliohms. Switching times are limited to 25ns for both turn-on and turn-off. Leakage current is specified at a maximum of 3nA, with charge injection of -125pC. The component supports an operating temperature range from -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST configuration providing independent signal routing capabilities
• Low on-resistance ensures minimal signal attenuation across the passband
• Compact surface-mount packaging suitable for space-constrained designs

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal multiplexing in data acquisition systems
• Audio path switching in portable devices
• Test and measurement equipment signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the specific listing indicates non-compliance. Validate package integrity upon receipt to ensure solder joint reliability during assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Compare against the ISL43L712IU variant if MSOP packaging is preferred over TDFN. Ensure supply voltage constraints align with the 1.65V to 3.6V operational window. Evaluate thermal management needs given the small form factor and power dissipation characteristics under load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ISL43L71x family of analog switches. It shares core electrical characteristics with variants like the ISL43L710 and ISL43L711, differing primarily in packaging options such as TDFN or MSOP. The manufacturer transitioned from Intersil to Renesas Electronics Corporation, affecting branding but not internal architecture.
