ISL43240IAZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43240IAZ is a quad single-pole double-throw (SPDT) analog switch IC manufactured by Renesas Electronics. It features four independent channels within a single package, designed for signal routing applications. The device operates with a supply voltage range of 2V to 12V for single supply or ±1V to ±6V for dual supply configurations. Key electrical parameters include a maximum on-resistance of 25 Ohms and a typical on-resistance of 18 Ohms at ±5V. Switching speeds are characterized by a maximum turn-on time of 65 ns and a maximum turn-off time of 50 ns. The component supports a continuous DC switch current of 30 mA and draws a maximum supply current of 1 µA. It is housed in an SSOP-20 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm exact packaging and temperature grade variants. Confirm RoHS compliance status through the manufacturer's current product change notices. Ensure that the SSOP-20 package dimensions match your PCB footprint requirements prior to finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple independent signal paths require switching within a limited board area. Consider the 25 Ohm maximum on-resistance limit for applications sensitive to signal attenuation. Verify that the required signal levels remain within the specified supply voltage constraints to prevent channel damage or performance degradation during operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43240 belongs to the broader family of quad SPDT analog switches produced by Renesas and its predecessor Intersil. This series is engineered to replace older discrete transistor-based switching solutions with integrated monolithic alternatives. The device maintains compatibility with standard logic control interfaces while offering improved consistency and reduced parasitic effects compared to manual switching mechanisms.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult official cross-reference lists for direct pin-compatible substitutes such as the ISL43240IV-T variant which utilizes a TSSOP-20 package. Verify functional equivalence regarding on-resistance and switching speed before substituting components from different manufacturers.
