MAX4523ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4523ESE+T is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four switches with two normally closed and two normally open configurations. The device operates from dual supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include an on-resistance of 100Ω max at ±5V supplies, an on-resistance flatness of 12Ω max, and off-leakage current of 1nA at +25°C. The package is a 16-pin Narrow SOIC.

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 product documentation. Cross-reference the part number with the latest datasheet revision to confirm pinout and electrical specifications remain unchanged.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed analog switching is required within a single package. Consider the on-resistance and leakage current specifications relative to the application's signal integrity requirements. Verify that the operating voltage range aligns with the system's available power rails. Evaluate the thermal performance and package type for suitability in the target PCB layout.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4523 is part of the MAX4521/MAX4522/MAX4523 family of quad, low-voltage, SPST analog switches. While the MAX4521 provides four normally closed switches and the MAX4522 offers four normally open switches, the MAX4523 combines two of each type. This family shares common electrical characteristics and pinouts, differing primarily in the internal switch configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same family include the MAX4521CSE and MAX4522CSE, though these offer different switch configurations (all NC or all NO). For applications requiring identical functionality, verify availability of other MAX4523 variants such as MAX4523EPE or MAX4523EEE if package changes are acceptable.
