MAX4543ESA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4543ESA+T 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) switch, supporting SPST or SPDT configurations. The device offers a maximum on-resistance of 60Ω with 2Ω matching between channels and 6Ω flatness. Key electrical parameters include a maximum charge injection of 5pC, turn-on time of 100ns, and turn-off time of 75ns at +5V. Supply current is typically less than 1µA, resulting in low power consumption of approximately 5µW. The component operates within a temperature range of -40°C to +85°C and utilizes an 8-pin SOIC package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features guaranteed break-before-make timing for the NO and NC switches.
• Provides TTL/CMOS logic compatibility with rail-to-rail input drive capability.
• Supports bidirectional signal switching across the entire supply voltage range.

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated systems requiring low power consumption
• Sample-and-hold circuits
• Audio and video switching applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing this part number. Confirm that the 'E' designation corresponds to the extended industrial temperature range of -40°C to +85°C. Ensure the ordering documentation matches the exact manufacturer part number to avoid discrepancies in package type or electrical specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4543ESA+T when a mixed configuration of normally open and normally closed switches is required within a single package. This model is suitable for designs needing guaranteed break-before-make timing, which distinguishes it from the MAX4541 and MAX4542 variants. Verify that the 60Ω maximum on-resistance meets the signal integrity requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4541–MAX4544 family of low-voltage, single-supply analog switches manufactured by Analog Devices / Maxim Integrated. While the MAX4541 contains two normally open switches and the MAX4542 contains two normally closed switches, the MAX4543 specifically combines one of each type. The family shares common electrical characteristics such as low leakage and fast switching speeds.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4541ESA+T and MAX4542ESA+T are pin-compatible members of the same family but differ in switch polarity. The MAX4544ESA+T is also pin-compatible but functions as a single-pole double-throw (SPDT) switch rather than a dual SPST configuration.
