MAX398CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398CSE+T is a precision, monolithic CMOS analog multiplexer housed in a 16-pin Narrow SOIC package. It provides eight bidirectional channels with an on-resistance of 225 ohms maximum at +5V single supply and 100 ohms maximum under dual supplies. The device operates from +3V to +15V single or ±3V to ±8V bipolar supplies. Key electrical characteristics include low charge injection (less than 5pC), fast transition times (under 250ns), and rail-to-rail signal handling capabilities.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range (0°C to +70°C) and the narrow SOIC-16 package configuration. Confirm RoHS compliance status for the '+T' tape-and-reel variant if applicable to your manufacturing process. Ensure the ordering code matches the exact pinout and thermal requirements for your PCB layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer is required with high channel-to-channel resistance matching. It is suitable for applications needing low leakage current and fast switching speeds under low-voltage conditions. Consider the dual-supply operation capability if bipolar signal ranges are necessary for the application design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX398/MAX399 family of precision analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. The MAX398 variant specifically offers eight channels, whereas the MAX399 provides two independent four-channel sets. Both share identical fabrication processes and core performance specifications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin compatibility with the DG408, DG409, DG508A, and DG509A. These industry-standard parts can be considered as direct functional replacements provided their electrical parameters meet the system requirements.
