MAX4521EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521EUE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed (NC) switches housed in a 16-pin TSSOP package with an operating temperature range of -40°C to +85°C. The device supports dual supplies from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include a maximum on-resistance of 100Ω, an on-resistance match of 1Ω, and an on-resistance flatness of 12Ω. Turn-on time is typically 45ns and turn-off time is typically 15ns at +25°C. Supply current is limited to 1µA maximum.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix 'EUE+' corresponds to the extended temperature range (-40°C to +85°C) and the TSSOP-16 surface-mount package. Ensure that the ordering information matches the required normally closed configuration distinct from the MAX4522 variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST switch with normally closed logic is required for low-voltage applications. The MAX4521 differs from the MAX4522, which utilizes normally open switches, and the MAX4523, which combines both types. Consider the 100Ω on-resistance and 1µA supply current constraints relative to the system's power budget and signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX452x family of quad, low-voltage analog switches. The MAX4521 specifically provides four normally closed switches, whereas the MAX4522 offers four normally open switches, and the MAX4523 contains two of each. All variants share similar electrical characteristics and pinouts, differing primarily in their default switch states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4522EUE+ serves as a functional substitute if the application requires normally open (NO) switches instead of normally closed (NC) switches, provided the logic inversion is accommodated in the design.
