MAX4521CEE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521CEE+T 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 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. Switching times are specified as 80ns turn-on and 30ns turn-off.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm the specific suffix indicates tape and reel packaging if required for automated assembly. Ensure the ordering code matches the exact temperature grade and package variant needed for the design. Cross-reference the datasheet revision to confirm pinout consistency before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST normally closed configuration is required within a compact QSOP footprint. Verify that the 100Ω maximum on-resistance meets the signal integrity requirements of the application circuit. Ensure the supply voltage constraints align with the system's available power rails. Consider the thermal dissipation limits inherent to the plastic QSOP package during continuous operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4521/MAX4522/MAX4523 family of low-voltage analog switches. The MAX4521 specifically denotes the variant containing four normally closed switches, distinguishing it from the MAX4522 (normally open) and MAX4523 (mixed NC/NO). The CEE suffix identifies the commercial temperature range and QSOP package style.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4521CSE, MAX4521EPE, and MAX4521CGE, which share identical electrical characteristics but differ in package type or temperature rating. Verify pin compatibility and thermal performance when substituting across different package codes.
