MAX398EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398EPE is a precision, monolithic CMOS analog multiplexer featuring eight channels in a 16-pin Plastic DIP package. It operates with single +3V to +15V or bipolar ±3V to ±8V supplies. The device guarantees an on-resistance of less than 100 Ω, matched within 6 Ω between channels, and remains flat over the specified signal range. It offers low off-leakage current (less than 2.5 nA at +85°C) and fast switching speeds with transition times under 250 ns. Designed for low-voltage applications, it provides rail-to-rail signal handling and CMOS-logic input compatibility.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Pin-compatible with industry-standard DG408/DG409/DG508A/DG509A devices
• Guaranteed on-resistance matching between channels within 6 Ω
• Low power consumption with less than 300 µW typical dissipation
• Rail-to-rail signal handling capability across the supply range

• 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 component revision and manufacturing date code against the latest Analog Devices documentation. Confirm that the plastic DIP package meets the required thermal derating specifications for your specific operating environment. Ensure proper power-supply sequencing during installation to prevent permanent damage from overvoltage conditions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when high channel count and precision are required in a through-hole format. It serves as a direct drop-in replacement for legacy DG408 designs. Consider the MAX399 if only four channels are needed, or the MAX398EEE/QSOP variant for surface-mount assembly requirements while maintaining identical electrical performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX398/MAX399 family of low-voltage CMOS analog multiplexers manufactured by Maxim Integrated, now part of Analog Devices. The 'E' suffix indicates an extended temperature range of -40°C to +85°C, suitable for industrial applications. The 'P' suffix designates the standard 16-lead Plastic Dual In-Line Package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include the DG408, DG409, DG508A, and DG509A due to pin compatibility. For equivalent performance in a different package, consider the MAX398EEE (QSOP) or MAX398ESE (Narrow SOIC). Verify that any replacement maintains the required on-resistance matching and leakage characteristics.
