ISL43240IA

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43240IA is a quad single-pole double-throw (SPDT) analog switch manufactured by Renesas Electronics. It features four independent channels within a single package, supporting both single and dual power supply configurations. The device operates with a minimum supply voltage of 2 V for single supply or 1 V per rail for dual supplies, up to a maximum of 12 V single or 6 V dual. Key electrical parameters include a maximum on-resistance of 25 Ohms, a maximum switching time of 65 ns, and a maximum off-time of 50 ns. It draws a maximum supply current of 1 uA and supports a continuous DC switch current of 30 mA. The component is rated for an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix (e.g., IA vs IAZ) against the manufacturer's datasheet to confirm package type and temperature grade. Confirm availability status as some variants may be obsolete or restricted. Ensure compliance with RoHS directives if required for the target market.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPDT configuration is required for low-voltage analog signal routing. Compare on-resistance and leakage current specifications against alternative parts if high precision is needed. Verify that the 30 mA continuous current rating meets the load requirements of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43240 belongs to the ISL4324x family of quad SPDT analog switches. This series is designed for general-purpose signal switching applications requiring low power consumption and moderate speed. The 'IA' designation typically refers to the industrial temperature grade and specific packaging variant.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for pin-compatible alternatives such as the MAX4066 or ADG708 if sourcing is difficult. Verify that substitute devices meet the same voltage, resistance, and switching speed requirements.
