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 operating from a single +2V to +12V supply. The device guarantees an on-resistance of 100Ω max at +5V and 46Ω max at +12V, with channel matching within 4Ω max and flatness over the signal range of 18Ω max. Off-leakage current is limited to 1nA at +25°C and 2nA at +85°C. It operates in the commercial temperature range of 0°C to +70°C and is housed in a 14-pin Narrow SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official datasheet specifications before integration. Confirm that the 14-pin Narrow SO package aligns with the PCB footprint requirements. Ensure the operating environment remains within the specified 0°C to +70°C commercial temperature range. Validate that the single-supply voltage does not exceed the absolute maximum ratings to prevent permanent damage.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when normally closed switching states are required for the application logic. Compare against the MAX4610 if normally open switches are needed instead. Consider the MAX4612 if a mixed configuration of two normally open and two normally closed switches is preferred. Verify that the narrow SO package dimensions fit the available board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage, quad, SPST CMOS analog switches. The MAX4611 variant specifically provides four normally closed channels, distinguishing it from the MAX4610 which offers four normally open channels. All variants share identical pinouts and electrical characteristics regarding resistance and leakage.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4610CSD+ serves as a functional substitute if normally open switches are acceptable. The MAX4612CSD+ is an alternative for mixed NO/NC configurations. Cross-reference the MAX4611ESD+ for extended industrial temperature ranges (-40°C to +85°C). Verify pin compatibility and package dimensions before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the switches in the MAX4611?

The MAX4611 contains four normally closed (NC) switches, meaning the analog signal path is connected between the COM and NC terminals when the logic input is low.

How does the on-resistance vary with supply voltage?

The on-resistance is guaranteed at 100Ω max with a +5V supply and decreases to 46Ω max with a +12V supply.

Is the MAX4611 compatible with standard TTL logic levels?

Yes, the digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply.
