MAX4542CUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4542CUA is a precision, dual analog switch designed for single-supply operation from +2.7V to +12V. It features two normally closed (NC) switches within an 8-pin µMAX package. The device operates over a temperature range of 0°C to +70°C. Key electrical parameters include a maximum on-resistance (RON) of 60Ω at +5V supply, with a typical value of 33Ω. On-resistance matching between channels is guaranteed at a maximum of 2Ω, and RON flatness is limited to 6Ω max. Charge injection is capped at 5pC. Switching speeds are characterized by a maximum turn-on time (tON) of 100ns and a maximum turn-off time (tOFF) of 75ns at +5V. Supply current is typically less than 1µA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUA' corresponds to the commercial temperature grade (0°C to +70°C) and the 8-pin µMAX package format. Confirm that the ordering code matches the exact pinout for the dual NC switch variant. Cross-reference the manufacturer's latest datasheet revision to ensure no design changes affect compatibility or specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPST normally closed configuration is required for low-voltage single-supply applications. Ensure the system operates within the 0°C to +70°C temperature range. Verify that the 60Ω maximum on-resistance meets the signal integrity requirements of the application circuit. Consider the 8-pin µMAX package dimensions for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 family of low-voltage, single-supply dual analog switches. While the MAX4541 offers two normally open switches, the MAX4542 specifically provides two normally closed switches. 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 package options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4541CUA serves as a functional substitute if the application requires normally open switches instead of normally closed ones, maintaining identical pinouts and electrical specs. Other family members like the MAX4543CUA offer mixed NO/NC configurations in the same package.
