ISL43120IH-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43120IH-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. Electrical specifications include a maximum charge injection of 5pC, off-state leakage current of 100pA, and crosstalk of -105dB at 1MHz. Switching times are specified as 35ns for turn-on and 30ns for turn-off. The component supports an operating temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST configuration providing two independent signal paths within a compact footprint.
• Low on-resistance characteristic ensuring minimal signal attenuation across the conduction path.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout compatibility and electrical tolerances. Ensure the procurement source provides valid RoHS3 compliance certificates. Confirm that the delivered components match the SOT-23-8 package dimensions and marking requirements specified in the manufacturer datasheet.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel analog switch with moderate on-resistance is required for single-supply operation up to 12V. Consider the 20-ohm on-resistance and 5pC charge injection limits relative to the target signal integrity requirements. Verify that the SOT-23-8 package size fits the available board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43120 family of analog switches. It shares functional similarities with other members like the ISL43121 but differs in contact configuration. The device is designed for general-purpose analog signal switching where low power consumption and small package size are prioritized over ultra-low on-resistance.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ISL43121IH-T serves as a direct alternative within the same family, offering identical electrical parameters but utilizing a normally closed contact configuration instead of normally open. Verify that the change in contact state aligns with the circuit design requirements before substitution.
