MAX4543EKA-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4543EKA-T is a precision, dual analog switch designed for single-supply operation from +2.7V to +12V. It features one normally open (NO) and one normally closed (NC) SPST channel, enabling SPDT functionality. 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 low power consumption of 5µW and offers fast switching speeds, with turn-on time up to 100ns and turn-off time up to 75ns at +5V. It provides guaranteed break-before-make timing and supports TTL/CMOS logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the E suffix corresponds to the extended temperature range of -40°C to +85°C. Ensure compatibility with SOT-23-8 footprint requirements during PCB layout. Check for RoHS compliance status as indicated in official documentation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring mixed NO/NC configurations within a dual-channel package. Consider the 60Ω maximum on-resistance limit for signal integrity requirements. Evaluate the 5pC charge injection specification for sensitive analog signal paths. Verify that the single-supply voltage range aligns with the system's power architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4541–MAX4544 family of low-voltage, single-supply analog switches. While the MAX4541 contains two NO switches and the MAX4542 contains two NC switches, the MAX4543 specifically combines one NO and one NC switch. This configuration allows it to function as an SPDT switch or provide complementary switching signals.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4543EUA is a pin-compatible alternative available in the µMAX package. Other family members like the MAX4541 and MAX4542 share similar electrical characteristics but differ in switch configuration. Verify package dimensions and pinout compatibility before substitution.
