MAX4656EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4656EUA+ is a single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of ±4.5V to ±20V for dual supplies or +9V to +40V for single-supply configurations. The device features a maximum on-resistance of 10Ω at ±15V supplies and supports up to 300mA continuous current and 400mA peak current. It utilizes an 8-pin µMAX package with an exposed paddle, operates from -40°C to +85°C, and includes TTL/CMOS compatible logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Ensure the component matches the required electrical specifications for the target application environment. Cross-reference part numbers with authorized distributors to confirm availability and authenticity before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high continuous and peak current switching is required alongside low on-resistance. Consider the exposed paddle option if thermal dissipation is critical for the application. Verify that the supply voltage range aligns with the system's power architecture and that the logic input levels are compatible with the controlling circuitry.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4655–MAX4658 family of high-current CMOS analog switches. The MAX4656 variant specifically provides a normally open configuration, distinguishing it from the normally closed MAX4655. It shares pinout compatibility with other industry-standard switches while offering superior current handling capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet indicates pin compatibility with DG417 and DG418 devices. Verify functional equivalence regarding current ratings and on-resistance before substitution.
