MAX399CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX399CSE+T is a precision, monolithic CMOS analog multiplexer featuring two independent 4-to-1 channels in a 16-pin Narrow SOIC package. It operates with single +3V to +15V or bipolar ±3V to ±8V supplies. Key electrical parameters include a maximum on-resistance of 100Ω, channel matching within 6Ω, and low off-leakage current under 2.5nA at +85°C. The device supports rail-to-rail signal handling, TTL/CMOS logic compatibility, and offers ESD protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'T' indicates tape-and-reel packaging when sourcing this specific variant. Confirm the 'C' designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure the manufacturer is identified as Analog Devices Inc. or Maxim Integrated to guarantee component authenticity and datasheet alignment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX399CSE+T for applications requiring dual 4-channel multiplexing with low voltage operation. This part is appropriate where pin compatibility with legacy DG4xx series is required. Consider the narrow SOIC package constraints and ensure the system design accommodates the specified single or bipolar supply ranges for optimal performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX398/MAX399 family of precision analog multiplexers manufactured by Analog Devices (Maxim Integrated). The MAX399 specifically provides dual 4-channel functionality, contrasting with the MAX398's 8-channel configuration. Both share identical fabrication processes and electrical characteristics tailored for low-voltage CMOS applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed pin-compatible substitutes include DG409, DG509A, and their variants from other manufacturers. Verify that alternative parts meet the same on-resistance flatness and leakage specifications if replacing the MAX399CSE+T in existing designs.
