MAX4541CUA-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4541CUA-T is a precision, dual analog switch designed for single +2.7V to +12V supply operation. It features two normally open (NO) SPST switches within an 8-pin µMAX package. The device operates across a temperature range of 0°C to +70°C. Key electrical parameters include a maximum on-resistance (RON) of 60Ω at +5V, with a typical value of 33Ω. On-resistance matching between channels is guaranteed at a maximum of 2Ω, and RON flatness is limited to 6Ω max. Charge injection is capped at 5pC. Switching speeds are characterized by a maximum turn-on time (tON) of 150ns and a maximum turn-off time (tOFF) of 100ns. Supply current is typically less than 1µA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual single-pole/single-throw configuration with two independent normally open switches
• Low power consumption suitable for battery-powered equipment
• TTL/CMOS logic compatible inputs allowing direct interfacing with standard digital controllers
• High ESD protection rating exceeding 2000V per Method 3015.7

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated systems requiring low standby power
• Sample-and-hold circuits in data acquisition systems
• Audio and video signal routing and switching
• Heads-up displays and guidance control systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing from distributors. Confirm the 'C' designation aligns with the commercial 0°C to +70°C operating temperature range required for the application environment. Ensure the 8-pin µMAX package footprint matches the PCB layout constraints before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPST configuration with normally open contacts is required. The MAX4541 differs from the MAX4542 (normally closed) and MAX4543 (mixed NO/NC). Consider the MAX4544 if a single-pole/double-throw function is needed instead. Verify that the 60Ω maximum on-resistance meets the signal integrity requirements of the target circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4541 belongs to the MAX4541–MAX4544 family of low-voltage, single-supply analog switches manufactured by Analog Devices Inc./Maxim Integrated. This series provides precision switching capabilities with low distortion and fast switching times. The family includes variations in contact configuration and package types to support diverse system integration needs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4541CSA serves as a pin-compatible replacement offering the same SOIC-8 package option. For extended temperature ranges, the MAX4541EUA or MAX4541ESA provide -40°C to +85°C operation while maintaining functional compatibility.
