MAX394CWP+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394CWP+T is a low-voltage, quad single-pole/double-throw (SPDT) analog switch in a 20-pin Wide SO package. 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 offers 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 authenticity and specifications. Ensure the ordering suffix matches the required temperature range and packaging format. Cross-reference the manufacturer part number with authorized distributors to validate availability and compliance status before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPDT configuration with low voltage operation is required. Verify that the supply voltage range aligns with system requirements, as the device supports both single and dual supplies. Confirm that the Wide SO package fits the PCB layout constraints and thermal management needs of the design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX394 family of precision analog switches manufactured by Analog Devices/Maxim Integrated. It replaces older models like the MAX333A and maintains pin compatibility with the MAX333. The C suffix indicates a commercial temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX394 is pin-compatible with the MAX333 and MAX333A. Designers upgrading from these legacy parts should verify that the new on-resistance and leakage characteristics meet the specific application requirements.
