MAX394EWP+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394EWP+T is a low-voltage, quad single-pole/double-throw (SPDT) analog switch. It operates with 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 and guarantees matching within 2Ω between channels. It provides rail-to-rail analog signal handling, break-before-make switching with a typical delay of 10ns, and turn-off times under 75ns. Quiescent current remains below 1μA, making it suitable for portable applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWP' corresponds to the Wide SO package and -40°C to +85°C temperature range. Confirm RoHS compliance via the '+' designation in the ordering information. Ensure the component source matches Analog Devices specifications before integration into designs requiring precise thermal performance.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low power consumption and high voltage flexibility. The E-grade variant ensures extended temperature coverage compared to C-grade parts. Verify that the required on-resistance match and leakage currents align with the electrical characteristics provided for the specific operating voltage conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX394 family of precision analog switches. It serves as a direct pin-compatible replacement for older models like the MAX333 and MAX333A. The device utilizes Maxim's low-voltage silicon-gate process to achieve extremely low charge injection and high electrostatic discharge protection capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX394EWP+T is explicitly documented as a pin-compatible replacement for the MAX333 and MAX333A. Designers should verify that the legacy components' absolute maximum ratings and dynamic parameters are compatible with the MAX394 specifications during migration.
