MAX4737EUD+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4737EUD+T is a quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +5.5V supply and features low on-resistance of 4.5Ω maximum at +3V and 3Ω maximum at +5V. The device offers rail-to-rail signal handling, less than 0.5nA leakage current, and high off-isolation of -55dB at 10MHz. Designed for USB 1.1 and audio applications, it provides break-before-make switching with a 300MHz bandwidth and CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range aligns with system requirements. Check RoHS compliance status if environmental regulations apply. Validate the ordering suffix against the specific datasheet revision.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high bandwidth are critical for signal integrity. Consider the TSSOP-14 package for standard surface-mount assembly. Evaluate the supply voltage range to ensure compatibility with system logic levels. Compare leakage current specifications against sensitive application requirements. Verify pinout compatibility if replacing existing designs.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4737 belongs to a family of low-voltage quad SPST analog switches that includes the MAX4738 and MAX4739 variants. These devices share similar electrical characteristics but differ in switch configuration, such as normally open or normally closed terminals. The series is designed for applications requiring minimal signal distortion and fast switching speeds in portable and battery-powered equipment.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the MAX4738EUD+ and MAX4739EUD+ within the same product family. Verify pin compatibility and switch configuration differences before substitution. Cross-reference electrical parameters to ensure equivalent performance in the target application.
