MAX394EAP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394EAP+ is a low-voltage, quad single-pole/double-throw (SPDT) analog switch fabricated with CMOS technology. It operates on bipolar supplies from ±2.7V to ±8V or a single supply of +2.7V to +15V. The device features an on-resistance of less than 35Ω at ±4.5V, guaranteed to match within 2Ω between channels and remain flat over the signal range. It provides break-before-make switching with turn-off times under 75ns and turn-on times under 130ns. Quiescent current is less than 1μA, making it suitable for portable applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices documentation to confirm specifications and authenticity. Ensure the SSOP-20 package matches the design requirements. Check for RoHS compliance status indicated by the suffix. Confirm that the operating temperature range aligns with the system environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPDT switch is required for low-voltage systems. It is appropriate for designs needing rail-to-rail signal handling and low power consumption. Verify that the logic input voltage levels match the system's control signals. Consider the thermal dissipation capabilities if multiple switches are active simultaneously in high-temperature environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX394 series includes variants such as the MAX394CPP, MAX394CWP, and MAX394MJP, offering different temperature ranges and packaging options. The E-series parts, including the MAX394EAP+, support extended industrial temperatures from -40°C to +85°C. This specific part number denotes the SSOP-20 package variant within the broader family of precision analog switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states that the MAX394 is pin-compatible with the MAX333 and MAX333A. Designers replacing these components should verify that the electrical characteristics of the substitute meet the original circuit requirements.
