ISL43141IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43141IR is a quad single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics Corporation. It integrates four independent 1:1 switching circuits within a compact 16-VFQFN package featuring an exposed thermal pad. The device supports dual power supplies ranging from ±2.6V to 6V or a single supply from 2.7V to 12V. Key electrical specifications include a maximum on-resistance of 65 ohms, channel-to-channel matching of 2 ohms, and low charge injection of 1 picocoulomb. Switching times are specified at 80 nanoseconds for turn-on and 30 nanoseconds for turn-off. The component operates across an industrial temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the obsolete status of this part number before initiating any procurement activities. Confirm whether existing inventory sources offer genuine components or if alternative sourcing strategies are required. Check for official discontinuation notices from the manufacturer to ensure long-term supply chain stability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Evaluate the 65-ohm on-resistance against the target application's signal loss requirements. Ensure the selected power supply voltages remain within the specified 2.7V to 12V single or ±2.6V to 6V dual range. Consider the 16-QFN package dimensions for PCB layout constraints and thermal management needs.

Analog Switches, Multiplexers, Demultiplexers Part Context
