MAX4521EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521EPE 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 Plastic DIP package with an operating temperature range of -40°C to +85°C. The device supports dual power 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. Switching times are specified as 80ns for turn-on and 30ns for turn-off.

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. Check for recent product change notifications regarding manufacturing status or material composition updates before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring normally closed analog switching paths. Ensure the application operates within the specified ±2V to ±6V dual supply or +2V to +12V single supply limits. Verify that the 100Ω maximum on-resistance meets the signal integrity requirements of the target application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage SPST analog switches. The MAX4521 variant specifically provides four normally closed switches, distinguishing it from the MAX4522 (normally open) and MAX4523 (mixed configuration). The EPE suffix denotes the extended temperature range and plastic DIP packaging.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include MAX4521ESE, MAX4521EEE, and MAX4521EUE, which share identical electrical specifications but differ in package style. Cross-family replacements require verification of pinout compatibility and on-resistance specifications.
