MAX4611ESD+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4611ESD+T is a low-voltage, quad, 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. Off-leakage current is specified at 1nA max at +25°C and 2nA max at +85°C. It provides 2kV ESD protection per Method 3015.7 and handles rail-to-rail analog signals. 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 lead-free/RoHS-compliant status and the narrow SOIC-14 package configuration. Confirm the temperature grade corresponds to the extended industrial range (-40°C to +85°C). Ensure the datasheet revision matches the required specifications for on-resistance and leakage parameters before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when normally closed switching states are required for the application design. Verify that the single-supply voltage range (+2V to +12V) aligns with the system power architecture. Consider the 100Ω maximum on-resistance at +5V operation to ensure it meets the signal integrity requirements of the connected circuitry without excessive voltage drop.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. While pin-compatible with industry-standard alternatives like the 74HC4066, it offers optimized performance for single-supply operations. The MAX4611 variant specifically distinguishes itself by providing four normally closed switches, contrasting with the MAX4610's normally open configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4611CUD+ serves as a functional replacement if the commercial temperature range (0°C to +70°C) is sufficient for the application environment. Verify that any substitute maintains the same NC configuration and package dimensions to ensure mechanical fit.

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 established when the logic input is low.

How does the MAX4611 handle analog signals relative to the supply rails?

It supports rail-to-rail signal handling, allowing analog signals to swing from GND to V+ across the entire specified operating temperature range.

Is the MAX4611 compatible with standard TTL logic levels?

Yes, the digital inputs have logic thresholds of +0.8V (max) for low and +2.4V (min) for high, ensuring compatibility with TTL and CMOS logic when using a single +5V supply.
