MAX4543EUA-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4543EUA-T is a low-voltage, single-supply dual SPST analog switch manufactured by Analog Devices under the Maxim Integrated brand. It operates within a supply voltage range of 2.7 V to 12 V and features a maximum on-resistance of 60 Ohms. The device supports a continuous DC switch current of 10 mA with a maximum power dissipation of 362 mW in its UMAX-8 package. Switching performance includes a maximum turn-on time of 100 ns and a maximum turn-off time of 75 ns. It functions reliably across an extended industrial temperature range from -40°C to +85°C while maintaining a maximum supply current of 1 µA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the UMAX-8 footprint matches the target PCB layout requirements before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring dual SPST switching with a wide single-supply voltage range up to 12 V. Compare against the MAX4643 series if lower on-resistance or higher speed is required, noting that alternative parts may operate at different voltage levels. Verify thermal constraints given the 362 mW power dissipation limit in the small outline package.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4543 family of low-voltage analog switches. It shares functional specifications with the MAX4543ESA+ variant but differs in physical packaging, utilizing the compact UMAX-8 form factor instead of the SOIC-8 package. Both variants offer identical electrical characteristics for dual SPST switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4543ESA+ serves as a pin-compatible alternative offering identical electrical specifications in a SOIC-8 package. Designers must verify footprint compatibility during substitution.
