MAX4611CSD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4611CSD is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed (NC) switches housed in a 14-pin Narrow SO package. The device operates from a single +2V to +12V supply with maximum on-resistance of 100Ω at +5V and 46Ω at +12V. Key electrical parameters include off-leakage current of 1nA at +25°C, turn-on time of 65ns max, and turn-off time of 28ns max. It offers rail-to-rail signal handling and TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CSD' corresponds to the 14-pin Narrow SOIC package and commercial temperature range (+0°C to +70°C). Confirm RoHS compliance status as standard parts may vary; lead-free versions typically carry a '+' suffix. Ensure the component matches the original Maxim Integrated specifications before integration into designs requiring precise impedance matching.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring normally closed analog switching paths within a compact surface-mount footprint. Compare against MAX4610 (normally open) or MAX4612 (mixed NO/NC) if circuit topology differs. Verify that the 100Ω maximum on-resistance meets system loss requirements at the intended operating voltage. Consider thermal derating limits when designing for high ambient temperatures.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. It shares pinout compatibility with industry-standard devices like the 74HC4066 but offers superior performance characteristics including lower leakage and better on-resistance flatness. The family supports single-supply operation optimized for +5V systems while extending functionality up to +12V.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same package include MAX4610CSD (Normally Open configuration) and MAX4612CSD (Mixed Normally Open/Normally Closed configuration). For extended temperature ranges, consider MAX4611ESD+ (-40°C to +85°C). Verify pin compatibility and logic thresholds when substituting.
