MAX4521EEE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521EEE+T is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. It operates with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. The device features an on-resistance of 100Ω maximum, matched between switches to 4Ω maximum, and flat within 12Ω over the specified signal range. Each switch handles rail-to-rail analog signals with off-leakage current of 1nA at +25°C and 10nA at +85°C. Digital inputs have +0.8V and +2.4V logic thresholds for TTL/CMOS compatibility. It is housed in a 16-pin QSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required package type and temperature rating. Ensure compliance with RoHS directives if applicable to your manufacturing process. Cross-reference the datasheet revision history to confirm the electrical characteristics align with your design requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST analog switch is required for low-voltage applications. Consider the MAX4522 or MAX4523 variants if normally open or mixed contact configurations are needed instead of the standard normally closed contacts provided by the MAX4521. Evaluate the on-resistance and leakage current specifications against your signal integrity requirements. Ensure the supply voltage range fits within the specified operational limits for both single and dual supply configurations.

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. Other members of the series include the MAX4522 with four normally open switches and the MAX4523 with two normally closed and two normally open switches. All share similar electrical characteristics and pinout structures.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4522EEE+T and MAX4523EEE+T, which offer different switch contact states but maintain identical electrical performance and packaging. Verify that the alternative part number meets the specific logic state requirements of your circuit design before implementation.
