MAX4541CSA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4541CSA is a precision, dual analog switch designed for single +2.7V to +12V supply operation. It features two normally open (NO) SPST switches within an 8-pin SO package. Key electrical parameters include a maximum on-resistance of 60Ω and a channel-to-channel matching of 2Ω at +5V. The device offers low leakage currents with a maximum off-leakage of 100pA and fast switching speeds, characterized by a maximum turn-on time of 150ns and turn-off time of 100ns. Power consumption is minimal at 5µW, making it suitable for battery-powered applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix CSA against official manufacturer documentation to confirm the narrow SOIC package type and commercial temperature range. Ensure compatibility with standard surface-mount assembly processes. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPST switch with normally open contacts is required. Verify that the 60Ω maximum on-resistance meets system signal integrity requirements. Confirm that the +2.7V to +12V single-supply voltage range aligns with the target application's power architecture and logic levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4541–MAX4544 family of low-voltage, single-supply dual analog switches. While the MAX4541 variant specifically provides two normally open switches, other members like the MAX4542 offer normally closed configurations. The family shares similar electrical characteristics but varies in contact state and available package options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes within the same series include the MAX4542CSA and MAX4543CSA. These alternatives share the same 8-pin SO package and electrical specifications but differ in switch contact states, requiring verification of logical functionality during replacement.
