MAX4543ESA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4543ESA+ 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, functioning as an SPDT device. Key electrical parameters include a maximum on-resistance of 60Ω, a maximum on-resistance flatness of 6Ω, and a maximum on-resistance match between channels of 2Ω at +5V. The device guarantees a maximum charge injection of 5pC and low leakage currents of 10nA max at +85°C. Switching speeds are specified with a maximum turn-on time of 100ns and a maximum turn-off time of 75ns. It operates within a temperature range of -40°C to +85°C and consumes less than 5µW of power.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm RoHS compliance status through manufacturer datasheets or authorized distributors before procurement. Ensure supply voltage requirements align with the component's operational limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel configuration with mixed NO and NC states is required in an 8-pin SOIC package. Verify that the 60Ω maximum on-resistance meets system impedance requirements. Confirm compatibility with TTL or CMOS logic levels for control signals.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4543ESA+ belongs to the MAX4541–MAX4544 family of low-voltage, single-supply analog switches. While the MAX4541 and MAX4542 offer two identical NO or NC switches respectively, the MAX4543 provides a mixed configuration. This distinguishes it from the MAX4544, which offers a standard SPDT topology.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4541ESA+ and MAX4542ESA+ share the same SOIC-8 package and pinout but differ in internal switch configuration. Direct substitution requires verifying if the specific NO/NC arrangement matches the circuit design requirements.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4543 and MAX4544?

The MAX4543 contains one normally open and one normally closed switch, whereas the MAX4544 contains two normally open switches configured as a single-pole double-throw (SPDT).

Does the MAX4543 support break-before-make switching?

Yes, the MAX4543 is guaranteed to have a break-before-make timing delay.
