MAX4543EUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4543EUA is a precision, dual analog switch designed for single +2.7V to +12V supply operation. It features one normally open (NO) and one normally closed (NC) channel. Key electrical parameters include a maximum on-resistance of 60Ω, a maximum on-resistance flatness of 6Ω, and a maximum charge injection of 5pC. The device operates with a positive supply current of 1µA maximum. Switching speeds are characterized by a maximum turn-on time of 100ns and a maximum turn-off time of 75ns at +5V. It provides over 2000V ESD protection per Method 3015.7 and functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status through the datasheet or manufacturer certification before procurement. Ensure compatibility with existing PCB footprints for the µMAX-8 package.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mixed NO/NC configuration is required within a dual-channel architecture. Verify that the 60Ω maximum on-resistance meets system signal integrity requirements. Confirm that the ±10mA continuous current rating aligns with load specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 family of low-voltage, single-supply analog switches. While other variants in the series offer different contact configurations such as dual NO or dual NC, the MAX4543 specifically integrates one NO and one NC switch. This configuration allows flexible routing without requiring external logic inversion.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4543EUA is pin-compatible with the MAX323, MAX324, and MAX325 devices. Designers may consider these alternatives if sourcing the primary part is difficult, provided their electrical characteristics meet the application requirements.
