MAX4611ESD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4611ESD 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. Off-leakage current is limited to 1nA at +25°C and 2nA at +85°C. It provides rail-to-rail signal handling, TTL/CMOS logic compatibility, and 2kV ESD protection per Method 3015.7. The component is housed in a 14-pin Narrow SO package and operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'ESD' confirms the 14-pin Narrow SOIC package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated by the '+' designation in official documentation. Cross-reference the manufacturer part number against the latest datasheet revision to ensure pinout and electrical specifications match design requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing low-voltage systems requiring normally closed analog switching paths. Ensure the supply voltage remains within the +2V to +12V range to maintain specified on-resistance and leakage characteristics. Verify that the load current does not exceed the continuous 20mA rating. Consider the 18Ω maximum on-resistance flatness for applications demanding consistent signal transmission across varying voltage levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4611 belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. While the MAX4610 offers four normally open switches and the MAX4612 combines two NO and two NC switches, the MAX4611 specifically provides four normally closed channels. All variants share identical pinouts and electrical performance profiles, differing only in their default switch states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4611 is pin-compatible with the industry-standard 74HC4066 and the MAX4066. When substituting these parts, verify that the alternative device supports the required +12V single-supply operation and maintains comparable on-resistance and leakage specifications for the target application environment.

Analog Switches, Multiplexers, Demultiplexers FAQ

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

The MAX4611 contains four normally closed (NC) switches. In their default state without active logic control, the connections between the COM and NC terminals are established.

How does the MAX4611 handle overvoltage conditions?

Signals on the NO_, NC_, COM_, or IN_ pins exceeding V+ or GND are clamped by internal diodes. To prevent damage, forward-diode current must be limited to the maximum continuous current rating of 20mA.

Is the MAX4611 compatible with standard logic families?

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