MAX4646EUT-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4646EUT-T is a single-pole, single-throw (SPST) normally closed analog switch manufactured by Analog Devices Inc. It operates from a +1.8V to +5.5V single supply and features a typical on-resistance of 2.5Ω at +5V. The device offers fast switching speeds with a maximum turn-on time of 15ns and turn-off time of 10ns. It provides rail-to-rail signal handling, low leakage current of ±0.25nA, and low distortion of 0.014%. Packaged in a 6-pin SOT-23 format, it supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure the component matches the required normally closed functionality. Cross-reference the datasheet revision date to validate electrical characteristics. Confirm RoHS compliance status through authorized distribution channels before final procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog path is required within low-voltage single-supply designs. Compare the 2.5Ω on-resistance against system impedance requirements. Evaluate the 15ns switching speed against signal bandwidth needs. Consider the SOT-23-6 footprint constraints during PCB layout planning.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4645/MAX4646 family of fast, low-voltage CMOS analog switches. The MAX4646 variant specifically provides a normally closed contact state, contrasting with the MAX4645's normally open configuration. Both share identical electrical specifications and pinouts, differing only in their default switch state upon power-up or logic input absence.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes include the MAX4645EUT-T if a normally open configuration is acceptable. Other Maxim Integrated SPST switches in the SOT-23-6 package may serve as alternatives provided they meet the 2.5Ω on-resistance and 5.5V supply limits.
