MAX4501CUK+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4501CUK+T is a single-pole/single-throw (SPST), low-voltage, single-supply CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates continuously with a single supply between +2V and +12V and handles Rail-to-Rail analog signals. The device features an off-leakage current of 1nA at +25°C and 10nA at +85°C. Digital inputs have 0.8V and 2.4V logic thresholds for TTL/CMOS compatibility at +5V. It is housed in a SOT23-5 package with a guaranteed on-resistance of 250Ω at +5V. Switching speeds are 75ns turn-on and 50ns turn-off.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required temperature range and packaging format. Ensure compliance with RoHS directives as indicated in the datasheet. Cross-reference the part number with the latest product documentation to confirm availability status and any potential obsolescence notices before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage single-supply operation and rail-to-rail signal transmission. Consider the 250Ω on-resistance and switching speeds when designing high-frequency or precision signal paths. Verify that the digital control logic levels align with the system's voltage requirements for reliable switching performance across the specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4501/MAX4502 family of low-voltage SPST CMOS analog switches. The MAX4501 variant is specifically designed as a normally open switch, while the MAX4502 is normally closed. Both share identical electrical characteristics and pin configurations, differing only in their default switch state upon power-up.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include the MAX4502CUK+T for normally closed functionality within the same package. Other family members like MAX4501EUK+T offer extended temperature ranges. Ensure substitute parts match the SOT23-5 footprint and electrical specifications for seamless integration.
