MAX4517CUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4517CUK-T is a single-pole/single-throw (SPST), normally closed, CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with dual supplies between ±1V and ±6V or a single supply from +2V to +12V. The device guarantees an on-resistance of 20Ω at ±5V supplies. Key electrical parameters include a maximum off-leakage current of 1nA at +25°C and 20nA at +85°C, and a maximum charge injection of 20pC. Switching speeds are specified as 100ns turn-on time and 75ns turn-off time. The component is housed in a SOT23-5 surface-mount package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-rail analog signal handling capability

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment
• Audio and video signal routing
• Low-voltage data-acquisition systems
• Communications circuits
• PCMCIA cards

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUK' corresponds to the commercial temperature grade (0°C to +70°C) and SOT23-5 package when sourcing. Confirm that the '-T' designation indicates tape-and-reel packaging if reel quantity is required for assembly. Cross-reference the manufacturer part number with distributor catalogs to ensure compatibility with existing inventory specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring a normally closed analog path with low distortion. Ensure the control logic voltage levels are compatible with the V+ reference, as inputs are not TTL-compatible. For single-supply applications, verify that the logic thresholds remain valid at the minimum supply voltage. Consider the MAX4516 if a normally open configuration is preferred instead.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4516/MAX4517 family of dual-supply, low-on-resistance CMOS analog switches. The MAX4517 variant specifically provides a normally closed state, contrasting with the MAX4516's normally open state. Both share identical pinouts and electrical characteristics, allowing for flexible design choices based on default signal path requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4516CUK-T is a pin-compatible alternative offering a normally open configuration. For single-supply operation, the MAX4514 series is recommended as a pin-compatible substitute.
