MAX4517CUK

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4517CUK is a single-pole/single-throw (SPST), CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally closed (NC) configuration and operates with dual supplies ranging from ±1V to ±6V. The device provides a maximum on-resistance of 20 Ohms, ensuring low signal attenuation. It supports rail-to-rail analog signal handling and exhibits an off-leakage current of 1nA at +25°C. The digital input is referenced to the positive power supply and maintains CMOS compatibility. Packaged in a compact SOT-23-5 format, it is designed for space-constrained applications requiring reliable analog switching.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Normally closed SPST configuration for specific circuit logic requirements
• Low on-resistance of 20 Ohms for minimal signal loss
• Dual-supply operation capability between ±1V and ±6V
• CMOS-compatible digital inputs referenced to positive supply

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-powered instrumentation systems
• Signal routing in data acquisition circuits
• Audio signal path switching
• Sensor interface multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the suffix 'C' indicates commercial temperature range (-40°C to +85°C). Confirm package type is SOT-23-5. Check RoHS compliance status as '+T' variants are typically lead-free while standard suffixes may vary. Ensure voltage ratings match system dual-supply constraints.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed state is required upon power-up or control deactivation. Compare against MAX4516 if a normally open configuration is needed instead. Verify that the ±1V minimum dual supply meets the lowest operating voltage of the target application environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4516/MAX4517 family of low-voltage, dual-supply analog switches. It shares pinout compatibility with the MAX4514 series but differs in supply requirements and default switch states. The MAX4517 specifically denotes the normally closed variant within this CMOS switch lineup.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4516EUK+T offers identical electrical characteristics and packaging but functions as a normally open switch. MAX4514CUK+T provides similar performance but is optimized for single-supply operation rather than dual-supply configurations.
