MAX4521CEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521CEE+ is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches housed in a 16-pin QSOP package with an operating temperature range of 0°C to +70°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, channel-to-channel matching of 1Ω, and off-leakage current of 1nA at +25°C. Turn-on time is typically 80ns and turn-off time is 30ns under standard conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type and temperature grade. Review the official datasheet for absolute maximum ratings to ensure operational safety within specified voltage and thermal limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring low-voltage operation with rail-to-rail signal compatibility. Ensure the power supply configuration aligns with the specified single or dual voltage ranges. Verify that the logic input thresholds are compatible with the driving circuitry levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4521/MAX4522/MAX4523 family of quad analog switches. The MAX4521 variant specifically provides four normally closed switches, distinguishing it from the MAX4522 (normally open) and MAX4523 (mixed NC/NO) configurations within the same series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4521CEE+ is listed as a direct replacement for the discontinued MAX4521CEE. Verify pinout compatibility and electrical specifications before substitution.
