ISL43L120IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L120IR is a dual-channel, single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 1.65V to 3.6V and features a maximum on-resistance of 250 milliohms. The device provides fast switching times with both turn-on and turn-off delays capped at 25ns. Key electrical specifications include a charge injection of -125pC, off-leakage current of 3nA maximum, and channel-to-channel matching of 5 milliohms. It is housed in an 8-TDFN (3x3) package with exposed pad and supports an operating temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'IR' corresponds to the required tape-and-reel packaging format. Check RoHS compliance status as indicated in official documentation, noting potential variations based on manufacturing date codes. Ensure storage conditions adhere to moisture sensitivity level requirements for surface-mount devices.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel analog switch is needed with very low on-resistance under low-voltage single-supply conditions. The 250mΩ Ron ensures minimal voltage drop across the switch path. Verify that the 1.65V minimum supply voltage aligns with the system power rail. Consider the 8-TDFN package dimensions for PCB layout constraints and thermal dissipation requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43L120IR belongs to the Intersil ISL43L12x family of low-voltage analog switches. This series is characterized by its ability to operate efficiently from a single low-voltage supply while maintaining high performance metrics such as low on-resistance and fast switching speeds. The part is designed for applications where space and power consumption are critical constraints.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the ISL43L12x family or other Renesas analog switch portfolios. Verify that any substitute matches the 250mΩ on-resistance, 1.65V-3.6V supply range, and 8-TDFN package outline. Cross-reference switching times and leakage currents to ensure functional equivalence.
