MAX4521CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521CSE+T is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. The device features four normally closed switches with a maximum on-resistance of 100Ω at ±5V supplies. On-resistance is matched between channels to 10Ω max and remains flat within 12Ω max over the specified signal range. Off-leakage current is typically 1nA at +25°C. The component supports rail-to-rail analog signals and includes 2kV ESD protection per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status through official manufacturer documentation. Ensure the specific part number variant aligns with design requirements for voltage ranges and pin configurations before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST switch with normally closed contacts is required. Verify that the application operates within the specified single or dual supply voltage limits. Consider the on-resistance specifications relative to the load current requirements. Ensure the logic input thresholds are compatible with the driving circuit's output levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4521/MAX4522/MAX4523 family of quad low-voltage analog switches. The MAX4521 specifically provides four normally closed switches, distinguishing it from the MAX4522 which offers normally open switches, and the MAX4523 which combines two of each type. All variants share similar electrical characteristics and pinout structures.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4522CSE+T serves as a functional substitute if normally open switches are acceptable instead of normally closed. The MAX4523CSE+T may be used where a mix of normally open and normally closed switches fits the circuit design. Verify pin compatibility and electrical parameters before substitution.
