ISL43140IBZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43140IBZ is a four-channel single-pole single-throw (SPST) analog switch integrated circuit manufactured by Renesas Electronics. It operates within a supply voltage range of 2 V to 12 V for single-supply configurations, or ±2 V to ±6 V for dual-supply applications. The device features a maximum on-resistance of 65 Ohms and supports a DC switch current of 10 mA. Switching performance includes a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. The component is housed in a 16-pin SOIC-Narrow package and is rated for an industrial operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

The ISL43140IBZ is listed as obsolete and no longer manufactured. Verification of availability requires checking authorized distributors for remaining stock or approved replacement components. Ensure that any substitute part maintains compatibility with the required 16-pin SOIC-Narrow package and electrical specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a low-cost, four-channel SPST switch is required for signals within the 2 V to 12 V range. The 65 Ohm on-resistance is suitable for general-purpose applications but may require consideration for high-precision analog paths. Verify that the 16-pin SOIC-Narrow footprint fits the design constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL4314x series of CMOS analog switches. It shares functional similarities with other members like the ISL43141, differing primarily in packaging options such as TSSOP or QFN variants. The series is designed for cost-sensitive applications requiring multiple independent switching channels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Verify cross-references with similar 4-channel SPST analog switches in 16-pin packages. Check datasheets for matching on-resistance, supply voltage ranges, and pinout compatibility before substitution.
