MAX4524LEUB+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4524LEUB+T is a low-voltage, single-supply CMOS analog switch configured as a 4-channel multiplexer/demultiplexer. It operates from a +2V to +12.6V supply and features an inhibit input to simultaneously open all switches. The device handles rail-to-rail analog signals with a maximum on-resistance of 100Ω at +12V and a typical off-leakage current of 2nA at +25°C. Digital inputs have 0.8V to 2.0V logic thresholds for TTL/CMOS compatibility. It is housed in a 10-pin µMAX package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and RoHS compliance status. Ensure that the component matches the required thermal and electrical specifications for the intended application environment before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact 4-channel multiplexer is required for low-voltage single-supply applications. Consider the 100Ω on-resistance and 200MHz bandwidth for high-speed signal switching requirements. Verify that the logic voltage levels align with the system's control interface constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4524L/MAX4525L family of low-voltage analog switches manufactured by Analog Devices Inc./Maxim Integrated. The MAX4524L variant specifically provides a 4-channel multiplexer configuration, while the MAX4525L offers a double-pole/double-throw switch topology within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers include MAX4524EUB+T and MAX4524CUB+T. These alternatives share similar functionality but may differ in package dimensions or electrical characteristics such as on-resistance and leakage current.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the function of the INH pin?

The INH (Inhibit) pin allows simultaneous opening of all switches. Driving INH high or connecting it to V+ turns all switches off, while driving it low or connecting it to GND enables normal operation.

How does the device handle analog signals exceeding the supply voltage?

Internal reverse ESD protection diodes are connected between each analog signal pin and both V+ and GND. If any analog signal exceeds V+ or goes below GND, one of these diodes conducts to clamp the voltage.

What is the typical charge injection value?

The typical charge injection is 0.8 pC when measured with a 1nF capacitor, guaranteed by design rather than production testing.
