Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against the official Maxim Integrated datasheet specifications before integration. Confirm that the SOT23-8 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the ordering information to validate the specific suffix codes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual normally closed switch topology is required within a compact surface-mount form factor. The low on-resistance and fast switching times make it suitable for high-frequency signal routing. Consider the single-supply voltage range when designing the power architecture. Verify compatibility with existing logic levels for control signals.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 family of low-voltage, single-supply analog switches. While the MAX4541 offers dual normally open switches, the MAX4542 specifically provides dual normally closed functionality. The MAX4543 combines one NO and one NC switch, and the MAX4544 offers a single-pole double-throw configuration. All variants share similar electrical characteristics and pinout structures.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4541CUA-T serves as a functional alternative if a dual normally open configuration is acceptable instead of normally closed. Other family members like the MAX4543EKA-T offer mixed NO/NC configurations. Verify pin compatibility and electrical parameter alignment before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the switches in the MAX4542?

The MAX4542 contains two dual normally closed (NC) switches, meaning the analog signal path is connected by default when the logic input is low.

Does the MAX4542 support break-before-make switching?

Yes, the MAX4542 guarantees break-before-make timing to prevent short circuits during switching transitions.

What is the maximum charge injection for this device?

The maximum guaranteed charge injection is 5pC, which helps maintain signal integrity in sensitive applications.
