MAX398ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398ESE+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 14Ω maximum and a channel-to-channel matching of 6Ω maximum. The device operates from a single +3V to +15V supply or bipolar ±3V to ±8V supplies. Key electrical parameters include an off-leakage current of less than 2.5nA at +85°C, charge injection under 5pC, and transition times under 250ns. It features rail-to-rail signal handling and TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required temperature grade and packaging format. Review the latest datasheet revision for any updates to absolute maximum ratings or pin configurations before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel configuration is required within a standard 16-pin footprint. Ensure the application voltage stays within the specified single or dual supply ranges. Verify that the logic input levels align with the system's TTL or CMOS standards to guarantee proper switching functionality.

Analog Switches, Multiplexers, Demultiplexers Part Context

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

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX398ESE+T is directly pin-compatible with the DG408, DG409, DG508A, and DG509A. These industry-standard alternatives can be used as substitutes if they meet the specific on-resistance and leakage requirements of the design.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX398 handle overvoltage conditions?

Internal diodes clamp signals on any terminal to the supply rails. For external protection, series blocking diodes can be added to the supply pins, though this reduces the usable analog signal range.

What is the maximum power dissipation for the SOIC package?

The continuous power dissipation for the Narrow SOIC package is 696mW at +70°C ambient temperature, derating by 8.7mW/°C above that threshold.

Can the device operate with unbalanced supply voltages?

Yes, the MAX398 supports unbalanced supplies, such as +10V and -5V, provided the difference between V+ and V- does not exceed 17V.
