ISL43L712IU

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L712IU is a dual single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation, formerly Intersil. Designed for low-voltage operation, it functions as a bidirectional signal path controller within a compact 8-MSOP surface-mount package. The device supports a single power supply range of 1.65V to 3.6V. Key electrical specifications include a maximum on-resistance of 250 milliohms and a channel-to-channel matching tolerance of 5 milliohms. It exhibits fast switching times of 25ns for both turn-on and turn-off transitions. Leakage current is limited to a maximum of 3nA, with charge injection specified at -125pC. The component operates reliably across an industrial temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'IU' against the manufacturer's current datasheet to confirm package type and material composition. Note that product status may be listed as obsolete or not recommended for new designs; confirm availability through authorized distributors. Ensure compliance with RoHS directives if required for the target assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated analog switches are required within a tight space constraint provided by the 8-MSOP footprint. The low 250mΩ on-resistance makes it suitable for applications demanding high signal fidelity. Verify that the system voltage falls within the 1.65V to 3.6V range and that digital logic levels are compatible with the control inputs at the operating voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43L7xx family of low-voltage analog switches. While sharing similar operational principles with other members like the ISL43L710 or ISL43L711, the ISL43L712 specifically denotes the dual SPST topology. The 'Intersil' branding reflects the historical manufacturer prior to its acquisition by Renesas Electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible alternatives within the ISL43L7xx series or newer Renesas analog switch families. Verify that any substitute maintains the same 8-MSOP package dimensions and electrical characteristics, particularly on-resistance and leakage current limits.
