MAX4648EUT+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4648EUT+T is a single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +9V to +36V supply or dual ±4.5V to ±20V supplies. The device features a maximum on-resistance of 25Ω and guaranteed flatness of 2Ω over the specified signal range. Off-leakage current is limited to 1nA max at +25°C. Switching speeds are characterized by turn-on and turn-off times of 100ns each under standard test conditions. The component is housed in a compact 6-pin SOT-23 package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm lead-free status and temperature range specifications. Ensure compatibility with existing PCB footprints for the SOT-23-6 package. Confirm that the component meets all required environmental standards for the intended deployment environment before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally open SPST configuration is required within the specified voltage ranges. Evaluate the 25Ω on-resistance against load requirements to ensure acceptable voltage drop. Consider the 100ns switching speed for timing-sensitive applications. Verify that the logic input thresholds align with the system's control voltage levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4647/MAX4648 series of CMOS analog switches. The MAX4648 variant specifically provides a normally open contact, distinguishing it from the MAX4647 which offers a normally closed configuration. Both share identical electrical characteristics and packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes include the MAX4647EUT+T for normally closed applications. Other compatible parts within the same family may offer similar pinouts and electrical parameters. Verify pin compatibility and electrical ratings before substituting any alternative components.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4647 and MAX4648?

The MAX4647 contains a normally closed (NC) switch, while the MAX4648 contains a normally open (NO) switch. All other electrical characteristics remain identical.

Can the MAX4648 handle digital signals?

Yes, the device conducts analog or digital signals equally well in either direction.

What is the maximum power dissipation for the SOT-23 package?

The continuous power dissipation is 696mW at an ambient temperature of +70°C, derating by 8.7mW/°C above this temperature.
