MAX4569EUK+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4569EUK+T is a single-pole/single-throw (SPST) normally closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +12V supply and features ±15kV ESD protection on the NO/NC terminals. The device provides a maximum on-resistance of 70Ω at a +5V supply and 120Ω at a +3V supply, with channel matching limited to 2Ω maximum. It handles Rail-to-Rail analog signals and maintains low off-leakage current of 0.5nA at +25°C. The component utilizes a 5-pin SOT23 package and supports TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Ensure that the selected variant matches the required lead-free and RoHS compliance standards for your manufacturing process. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring a normally closed SPST configuration within a compact SOT23 footprint. Consider the 70Ω on-resistance specification at +5V supplies when calculating signal attenuation. Verify that input logic thresholds align with your system's digital voltage levels to ensure reliable switching control under varying operating conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4561/MAX4568/MAX4569 family of low-voltage CMOS analog switches. While the MAX4561 offers SPDT functionality and the MAX4568 provides a normally open configuration, the MAX4569 specifically delivers a normally closed single-channel topology. All variants share identical pinouts and electrical characteristics regarding ESD protection and power supply ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4569EUK+T is pin-compatible with the MAX4514 and MAX4515. Designers may consider these alternatives if different switching configurations or specific legacy requirements are necessary while maintaining the same physical footprint.
