MAX398ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398ESE+ is a precision, monolithic CMOS analog multiplexer featuring eight bidirectional 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 an on-resistance of 60Ω to 100Ω (±5V dual supply) and 150Ω to 225Ω (+5V single supply), with channel matching within 6Ω. The device exhibits low off-leakage current (<2.5nA at +85°C), charge injection <5pC, and transition times under 250ns. Operating temperature range is -40°C to +85°C.

• Guaranteed on-resistance matching between channels within 6Ω
• Rail-to-rail signal handling capability across the full supply range
• TTL/CMOS-logic compatible inputs for reduced loading

Analog Switches, Multiplexers, Demultiplexers Applications

• Sample-and-Hold Circuits
• Automatic Test Equipment
• Heads-Up Displays
• Guidance and Control Systems
• Battery-Operated Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the industrial temperature range (-40°C to +85°C) and 'SE' indicates the Narrow SOIC package. Confirm RoHS compliance status via official documentation as '+'. Ensure pinout alignment with legacy equivalents if replacing older components in existing designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high channel count (8-channel) and precise resistance matching are required. Verify that the single-supply operation meets the voltage requirements, noting that switching speeds may increase at lower voltages like +3V compared to +5V. Ensure logic input levels align with the system's TTL/CMOS standards.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX398 is part of the Maxim Integrated precision analog multiplexer family, designed for low-voltage applications. It serves as a direct replacement for older industry-standard parts like the DG408, offering improved performance in terms of leakage current and switching speed while maintaining compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the DG408, DG508A, and their variants from other manufacturers. Verify that the substitute maintains similar on-resistance flatness and leakage specifications for critical signal integrity.
