MAX4501EXK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4501EXK-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 utilize 0.8V and 2.4V logic thresholds for TTL/CMOS compatibility at +5V. It is housed in a SC70-5 package and supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EXK-T confirms the SC70-5 package and industrial temperature grade (-40°C to +85°C). Ensure the component matches the standard MAX4501 configuration rather than the MAX4502 variant. Confirm RoHS compliance status through official manufacturer documentation prior to procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage single-supply operation and compact surface-mount packaging. Consider the guaranteed on-resistance limits and leakage currents relative to the specific supply voltage and temperature conditions of the target design. Verify that the input logic levels align with the system's control interface requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4501/MAX4502 family of low-voltage SPST CMOS analog switches. The MAX4501 variant is normally open, while the MAX4502 is normally closed. Both share identical electrical characteristics and pinouts, differing only in their default switch state upon power-up or reset.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum continuous current into any terminal?

The maximum continuous current into any terminal is ±10mA.

How does the logic threshold change with supply voltage?

At +5V, the thresholds are 0.8V and 2.4V. As V+ rises to +12V, the high-level threshold increases to approximately 3V, maintaining CMOS compatibility but exceeding the guaranteed TTL high-level minimum.

Are the NO, NC, and COM pins interchangeable?

Yes, the NO, NC, and COM pins are identical and interchangeable. Any pin can function as an input or output, allowing bidirectional signal flow.
