MAX4611CUD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4611CUD 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 within a 14-pin TSSOP package. The device operates from a single +2V to +12V supply and handles rail-to-rail analog signal levels from V+ to GND. Key electrical parameters include a maximum on-resistance of 100Ω at +5V supply and 46Ω at +12V supply. On-resistance is matched between channels to a maximum of 4Ω and remains flat over the specified signal range with a maximum variation of 18Ω. Maximum off-leakage current is specified as 1nA at +25°C and 2nA at +85°C. The component supports TTL/CMOS logic compatibility and offers 2kV ESD protection per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix for the MAX4611CUD model against official manufacturer documentation to confirm lead-free status and temperature range specifications. Confirm that the 14-pin TSSOP package variant matches the required footprint for the target PCB design. Ensure compliance with relevant environmental directives such as RoHS if applicable to the project requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4611CUD when a quad SPST configuration with normally closed contacts is required for low-voltage applications. This component is suitable for designs needing rail-to-rail signal transmission and TTL/CMOS logic interface compatibility. Consider the guaranteed on-resistance flatness and channel matching characteristics for precision signal switching tasks in data acquisition or audio routing systems.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4611CUD belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage, quad, SPST CMOS analog switches. While pin-compatible with industry-standard alternatives like the 74HC4066, this series distinguishes itself through optimized performance for single-supply operation up to +12V. The MAX4611 specifically provides four normally closed switches, contrasting with the MAX4610's normally open configuration and the MAX4612's mixed NO/NC arrangement.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4610 and MAX4612 are pin-compatible members of the same family but differ in switch contact states. Verify functional requirements regarding normally open versus normally closed configurations before substituting.
