MAX4611EPD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4611EPD 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 limited to 18Ω max. Maximum off-leakage current is specified as 1nA at +25°C and 2nA at +85°C. It operates in the extended temperature range of -40°C to +85°C and is housed in a 14-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EPD' corresponds to the 14-pin Plastic DIP package and the -40°C to +85°C industrial temperature grade. Confirm that the component is sourced from authorized distributors or directly from Analog Devices to ensure authenticity. Check for RoHS compliance status if required by assembly specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally closed configuration is required for signal paths. Ensure the application voltage does not exceed the absolute maximum rating of +13V. Verify that the logic input thresholds align with the system's TTL or CMOS levels, particularly when operating near the lower end of the supply voltage range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage analog switches. While pin-compatible with industry-standard 74HC4066 devices, it offers superior on-resistance matching and lower leakage characteristics. The MAX4611 variant specifically provides four normally closed channels, distinguishing it from the MAX4610 (normally open) and MAX4612 (mixed NO/NC).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4610CUD+ and MAX4611EUD+ are documented lead-free/RoHS-compliant alternatives within the same series. Verify that any replacement maintains the required normally closed configuration and matches the 14-pin Plastic DIP footprint.

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.

How does the on-resistance vary with supply voltage?

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 logic families?

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