MAX399ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX399ESE is a precision, monolithic CMOS analog multiplexer featuring dual 4-channel (2 x 4:1) configuration in a 16-pin Narrow SOIC package. It operates with single +3V to +15V or bipolar ±3V to ±8V supplies. Key electrical parameters include an on-resistance of 100Ω maximum at ±5V and 225Ω maximum at +5V single supply, with channel matching within 6Ω. The device offers low leakage current (<2.5nA at +85°C), charge injection under 5pC, and transition times under 250ns. It provides rail-to-rail signal handling and maintains TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range of -40°C to +85°C. Confirm the 'S' suffix indicates the 16-pin Narrow SOIC package format. Ensure the '+' suffix denotes compliance with RoHS standards. Cross-reference the manufacturer's latest ordering guide to confirm current production status and availability for this specific part number.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX399ESE when a dual 4-channel multiplexer is required instead of the single 8-channel MAX398. Verify that the system requires the narrow SOIC footprint rather than QSOP or Plastic DIP options. Ensure the application voltage range fits within the specified single or bipolar supply limits. Check if the 100Ω on-resistance meets the signal integrity requirements compared to lower resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX399ESE belongs to the Maxim Integrated MAX398/MAX399 family of precision analog switches. This series utilizes a low-voltage silicon-gate CMOS process to achieve flat on-resistance over the full analog signal range. The component is designed as a drop-in replacement for legacy industry-standard parts, facilitating upgrades in existing designs requiring improved precision and lower power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX399ESE is pin-compatible with the DG409, DG509A, and MAX399EEE variants. When replacing older components, verify that the new part's on-resistance and leakage specifications meet the original design constraints. Ensure the thermal management remains adequate for the Narrow SOIC package.
