ISL43120IHZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43120IHZ-T is a dual single-pole single-throw (SPST) normally-open analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 2.7V to 12V and is housed in an SOT-23-8 surface-mount package. The device features a maximum on-resistance of 20 ohms with a channel-to-channel matching of 800 milliohms. Key electrical specifications include a maximum charge injection of 5pC, off-state leakage current of 100pA, and a crosstalk performance of -105dB at 1MHz. Switching times are specified at 35ns for turn-on and 30ns for turn-off, supporting operation within a temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer part number ISL43120IHZ-T against official Renesas documentation to confirm authenticity. Ensure the component meets RoHS3 compliance requirements as specified in the datasheet. Check for any specific handling precautions related to electrostatic discharge during assembly. Confirm that the SOT-23-8 package dimensions align with your PCB layout constraints before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPST switch with moderate on-resistance is required for single-supply applications up to 12V. Consider the 20-ohm on-resistance limit for signal integrity requirements. Evaluate the 5pC charge injection specification against the sensitivity of the downstream circuitry. Ensure the operating temperature range of -40°C to 85°C matches the environmental conditions of the target application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43120 belongs to the ISL4312x family of analog switches, which are designed for general-purpose signal switching. This series offers a balance between speed, power consumption, and signal fidelity. The ISL43120 specifically provides dual SPST functionality, distinguishing it from multiplexer variants within the same product line. It serves as a fundamental building block for signal management in mixed-signal systems.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult official Renesas documentation for qualified replacement parts or pin-compatible alternatives. Verify that any substitute component matches the SOT-23-8 package and electrical specifications, including on-resistance and supply voltage range. Cross-reference switching times and charge injection values to ensure compatibility with existing circuit designs.
