ISL43L712IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L712IR is a dual-channel analog switch manufactured by Renesas Electronics Corporation, formerly Intersil. It features two single-pole single-throw (SPST) normally open/normally closed circuits 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. Charge injection is specified at -125pC, with off-state leakage current capped at 3nA. 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 within a compact footprint.
• Low on-resistance ensures minimal signal attenuation across the conduction path.
• Fast switching speeds support high-frequency data transmission requirements.
• Low charge injection preserves signal integrity during state transitions.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in portable battery-powered equipment
• Audio and video signal switching applications
• Data acquisition systems requiring low distortion

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IR' against the manufacturer's latest documentation to confirm pinout compatibility and RoHS status. The provided reference indicates this specific part number may be classified as obsolete or not compliant with current environmental standards. Confirm availability through authorized distributors and validate that the 8-TDFN package dimensions match the target PCB layout before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel switch with low on-resistance is required for single-supply operation below 3.6V. Ensure the application does not exceed the 250 milliohm resistance limit for signal fidelity. Verify that the 8-TDFN package size fits the mechanical constraints. Consider the -125pC charge injection value if driving sensitive capacitive loads where signal glitches must be minimized.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the ISL43L71x family of analog switches. It shares functional similarities with other members like the ISL43L710 and ISL43L711, differing primarily in internal circuit configuration and pin assignments. The 'IR' suffix typically denotes the industrial temperature grade and the specific tape-and-reel packaging format used for surface-mount assembly.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's obsolescence notices or cross-reference tools for direct replacements. Ensure any alternative device matches the 8-TDFN package and 1.65V to 3.6V supply range.
