MAX4611CPD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4611CPD 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 of 18Ω max over the signal range. Maximum off-leakage current is 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 Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature rating. The CPD suffix indicates a 14-pin Plastic DIP package with a commercial temperature range of 0°C to +70°C. Ensure compatibility with existing PCB footprints and thermal requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed configuration is required for signal switching. Compare against the MAX4610 (normally open) and MAX4612 (mixed NO/NC) variants if different logic states are needed. Verify that the 100Ω on-resistance meets the application's voltage drop constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage, quad, SPST CMOS analog switches. These devices are pin-compatible with industry-standard 74HC4066 switches and offer optimized performance for single-supply operations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4610CUD+ serves as a functional substitute if a normally open configuration is acceptable. For identical NC functionality, verify availability of other packages like the MAX4611EUD+ or MAX4611EPD+ based on board layout requirements.

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 signal path between COM and NC is connected when the logic input is low.

Does the MAX4611 support dual supplies?

No, the datasheet specifies operation from a single positive supply ranging from +2V to +12V.

How does the on-resistance vary with supply voltage?

On-resistance decreases as supply voltage increases; it is guaranteed at 100Ω max at +5V and 46Ω max at +12V.
