MAX4521CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521CPE 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 with an on-resistance of 100Ω maximum and a flatness of 12Ω maximum over the signal range. The device operates from dual supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include off-leakage current of 1nA at +25°C, turn-on time of 80ns maximum, and turn-off time of 30ns maximum under standard conditions. It provides 2kV ESD protection per Method 3015.7 and is housed in a 16-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm the specific ordering suffix matches the required temperature range and package type. Request official datasheets and RoHS compliance documentation prior to integration. Validate pin configurations against the latest manufacturer specifications to ensure correct circuit implementation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4521 variant specifically when normally closed switch states are required upon power-up. Compare on-resistance flatness and leakage current requirements against alternative models like the MAX4522 if normally open configurations are needed. Ensure supply voltages remain within the specified ±2V to ±6V dual or +2V to +12V single ranges to maintain performance guarantees.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4521 belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage SPST analog switches. This series shares identical pinouts and core switching characteristics, differing primarily in the default state of the internal switches. The MAX4521CPE represents the commercial temperature grade version packaged in a standard 16-pin Plastic DIP format.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same family include the MAX4522CPE (normally open) and MAX4523CPE (mixed NC/NO). Verify that any substitute maintains the required 16-pin PDIP footprint and compatible logic thresholds.
