MAX4611CSD+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4611CSD+T 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. Off-leakage current is specified at 1nA max at +25°C and 2nA max at +85°C. Switching times are 65ns max for turn-on and 28ns max for turn-off. It operates in the commercial temperature range of 0°C to +70°C and is housed in a 14-pin Narrow SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as the local source indicates unavailability. Confirm the specific ordering suffix matches the required package and temperature grade. Ensure the lead-free designation aligns with project compliance requirements before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when normally closed switching functionality is required for low-voltage applications. Compare against the MAX4610 if normally open switches are needed instead. Verify that the 100Ω on-resistance meets the system's voltage drop constraints at the intended load currents.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. The MAX4611 variant specifically provides four normally closed channels, distinguishing it from the MAX4610 which offers normally open channels. Both share identical electrical characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4610CSD+T serves as a functional substitute if normally open switches are acceptable. The MAX4612CSD+T may be used where a mixed configuration of two normally open and two normally closed switches is suitable.
