MAX4542CPA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4542CPA is a precision, dual analog switch designed for single +2.7V to +12V supply operation. It features two normally closed (NC) switches within an 8-pin Plastic DIP package and operates across a temperature range of 0°C to +70°C. The device offers low power consumption of 5µW, low leakage currents of 100pA maximum, and fast switching speeds with turn-on times up to 150ns and turn-off times up to 100ns. When powered from a +5V supply, it provides a maximum on-resistance of 60Ω, 2Ω maximum matching between channels, and 6Ω maximum on-resistance flatness.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CPA' corresponds to the 8-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm that the component meets RoHS compliance requirements if applicable to the target assembly process. Ensure the logic input levels match the system's voltage rails for proper TTL/CMOS compatibility during integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a dual normally closed analog switch is required for low-voltage applications. The MAX4542 differs from the MAX4541 by utilizing normally closed contacts instead of normally open ones. Consider the 8-pin DIP package constraints and the 0°C to +70°C operating temperature range against environmental conditions. Verify that the 60Ω maximum on-resistance meets the signal integrity requirements of the circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4542 belongs to the MAX4541–MAX4544 family of low-voltage, single-supply dual analog switches manufactured by Analog Devices Inc./Maxim Integrated. This series includes variants with different switch configurations, such as normally open or single-pole/double-throw arrangements. The MAX4542 specifically provides two normally closed switches, distinguishing it from other members like the MAX4541 which offers normally open switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4542ESA+ serves as a pin-compatible surface-mount alternative in an SOIC-8 package with an extended temperature range of -40°C to +85°C. Other family members like the MAX4541 provide similar electrical characteristics but feature normally open switches instead of normally closed ones.
