MAX4748EUD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4748EUD+ is a low-voltage, quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2V to +11V supply and features four normally closed (NC) switches. The device handles rail-to-rail analog signals with guaranteed on-resistance of 50Ω (max) at +3V and 25Ω (max) at +5V. It exhibits low leakage current (0.1nA max) and consumes less than 0.5nW typical quiescent power. Available in a 14-pin TSSOP package, it supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official datasheets for electrical parameters and pin configurations. Confirm RoHS compliance status and lead-free packaging specifications during acquisition. Ensure compatibility with system voltage requirements and thermal management constraints before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog switching function is required within a low-voltage environment. Consider the 14-pin TSSOP package for surface-mount applications requiring standard footprint dimensions. Evaluate the specific on-resistance and leakage characteristics against circuit sensitivity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4747–MAX4750 family of low-voltage analog switches. While sharing similar electrical characteristics and packaging options, the MAX4748EUD+ is distinguished by its four normally closed switch configuration, contrasting with the normally open switches found in other members of the series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Other members of the MAX4747–MAX4750 family may serve as alternatives depending on the required switch state. Verify that any substitute matches the specific NC or NO configuration needed for the application circuit.
