MAX4612CSD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4612CSD+ is a low-voltage, quad, single-pole/single-throw (SPST) CMOS analog switch in a 14-pin narrow SOIC package. It features two normally open and two normally closed switches operating from a single +2V to +12V supply. On-resistance is guaranteed at 100Ω max (+5V supply) and 46Ω max (+12V supply), with channel matching of 4Ω max and flatness of 18Ω max over the signal range. Off-leakage current is 1nA at +25°C and 2nA at +85°C. The device supports rail-to-rail signal handling, offers 2kV ESD protection, and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices documentation to confirm lead-free status and RoHS compliance. Ensure the ordering suffix matches the required package type and temperature range specifications. Cross-reference part numbers with authorized distributors to validate authenticity and traceability before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed analog switching is required in a low-voltage environment. Verify that the single-supply voltage range of +2V to +12V aligns with system requirements. Consider the 14-pin narrow SOIC package dimensions for PCB layout constraints and ensure thermal dissipation limits are respected during operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4612CSD+ belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. While pin-compatible with industry-standard devices like the 74HC4066, it offers superior performance characteristics including lower on-resistance and better channel matching. This specific variant provides a balanced configuration of two NO and two NC switches within a compact surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other members of the MAX461x family such as the MAX4610CSD+ or MAX4611CSD+, provided the switch configuration matches the application needs. Verify compatibility with existing PCB footprints and electrical parameters before substitution.
