MAX4645EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4645EUA+ is a single-pole, single-throw (SPST) CMOS analog switch in an 8-pin µMAX package. It operates from a +1.8V to +5.5V single supply with a typical on-resistance of 2.5Ω at +5V and a maximum flatness of 0.4Ω. The device features fast switching speeds of 12ns turn-on time and 8ns turn-off time. Off-leakage current is limited to 0.25nA maximum at +25°C. It supports rail-to-rail analog signals and offers low distortion of 0.014% typical.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the marking code against official documentation. Confirm the package type matches the required 8-pin µMAX configuration. Ensure the operating temperature range meets the application requirements of -40°C to +85°C. Cross-reference the datasheet revision to ensure compatibility with design specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low voltage operation and minimal board space. Consider the 2.5Ω on-resistance for signal integrity in low-distortion environments. Evaluate the power consumption against battery life requirements. Compare the switching speed with system timing constraints to ensure adequate performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4645/MAX4646 series of fast, low-voltage analog switches. The MAX4645 variant functions as a normally open switch, while the MAX4646 is normally closed. Both share similar electrical characteristics but differ in their default logic states. The series is designed for portable and battery-operated equipment.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the MAX4646EUA+ for complementary logic functionality within the same package. Other SPST switches from the Maxim portfolio may serve as alternatives if pinout and electrical parameters align with the design requirements.
