MAX398CSE+TG55

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398CSE+TG55 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 100Ω maximum at dual supplies and 225Ω maximum at single supply, with channel matching within 6Ω. The device offers low off-leakage current (less than 2.5nA at +85°C), charge injection under 5pC, and transition times under 250ns. It provides electrostatic discharge protection exceeding 2000V and maintains rail-to-rail signal handling capabilities.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'TG55' against official manufacturer documentation, as standard datasheets list 'CSE' for commercial temperature range Narrow SOIC packages without this suffix. Confirm that the ordering code corresponds to the intended temperature grade and packaging configuration before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring precise analog signal routing with minimal resistance variation across multiple channels. Ensure the operating voltage aligns with the specified single or bipolar supply ranges. Consider the 100Ω on-resistance limit for signal integrity requirements in data-acquisition or audio routing applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX398/MAX399 family of low-voltage CMOS analog multiplexers. The MAX398 variant specifically provides eight channels, whereas the MAX399 offers two independent four-channel configurations. Both share identical pinouts and core performance characteristics, facilitating flexible design implementations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the DG408, DG409, DG508A, and DG509A due to guaranteed pin compatibility. Verify that alternative components meet the specific on-resistance flatness and leakage current requirements defined in the original design specifications.
