MAX4748ETE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4748ETE+T is a low-voltage, quad single-pole double-throw (SPDT) analog switch operating from a single +2V to +11V supply. It features four normally closed (NC) switches with rail-to-rail signal handling and low leakage current of 0.1nA. At +5V, the on-resistance is 25Ω max with 3Ω matching; at +3V, it is 50Ω max with 3.5Ω matching. The device consumes less than 0.5nW quiescent power. It operates within -40°C to +85°C temperature range in a 16-pin Thin QFN package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure proper ESD handling procedures during storage and assembly. Validate package integrity upon receipt. Cross-reference ordering information with official datasheets to confirm exact suffix specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when normally closed analog switching is required in low-power designs. Verify supply voltage compatibility between +2V and +11V ranges. Consider thermal dissipation requirements for the TQFN package. Evaluate on-resistance flatness needs for precision signal paths. Check logic level compatibility with control circuitry.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4747-MAX4750 family of low-voltage analog switches. The MAX4748 variant specifically provides four normally closed switches, distinguishing it from the MAX4747 (normally open) and MAX4749/MAX4750 (mixed SPDT) configurations. All variants share similar electrical characteristics and packaging options including WLP, TSSOP, and TQFN.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4747ETE+T offers identical packaging but with normally open switches instead of normally closed. MAX4749ETE+T provides mixed NO/NC SPDT configuration. MAX4750ETE+T contains two SPDT switches. Direct functional replacement requires verifying switch state requirements match design needs.
