MAX4504CUK+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4504CUK+T is a low-voltage, dual-supply, 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 handles rail-to-rail analog signals and includes CMOS-logic compatible inputs without requiring a ground pin. Key electrical specifications include a maximum on-resistance of 250Ω at ±5V supplies, off-leakage current of 1nA at +25°C, and charge injection of 10pC maximum. Switching speeds are characterized by a turn-on time of 150ns and a turn-off time of 100ns. It is housed in a compact SOT23-5 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual-supply operation capability spanning ±1V to ±6V for flexible power configurations
• Normally closed (NC) SPST topology ensuring default signal path continuity
• CMOS-logic compatible input architecture eliminating the need for a dedicated ground pin

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment requiring low power consumption
• Audio and video signal routing systems
• Low-voltage data-acquisition systems
• Communications circuits and cellular phones
• PCMCIA cards and modems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates tape-and-reel packaging if required for automated assembly. Ensure the ordering code matches the exact temperature range and package variant needed for the design. Request original datasheets and test reports to validate compliance with specified electrical limits before integration into production lines.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog switch is required within a dual-supply environment. Compare against the MAX4503 if a normally open configuration is preferred instead. Consider the MAX4501/MAX4502 if single-supply operation is necessary, as they serve as pin-for-pin equivalents for that specific power constraint. Evaluate the SOT23-5 package size against available board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4503/MAX4504 family of low-voltage CMOS analog switches. The MAX4504 specifically denotes the normally closed variant, whereas the MAX4503 is normally open. Both share identical electrical characteristics and pinouts, differing only in their default switch state. The family supports various packages including DIP, SO, and SOT23-5 to accommodate different manufacturing needs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4503CUK+T serves as a functional substitute if a normally open configuration is acceptable. For single-supply applications, the MAX4501CUK+T or MAX4502CUK+T provide pin-compatible alternatives. Verify that any replacement maintains the required ±1V to ±6V operating voltage range and SOT23-5 footprint.
