Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'ESE' confirms the -40°C to +85°C industrial temperature range and the 16-pin Narrow SOIC package type. Confirm RoHS compliance by checking for the '+' designation if required by the manufacturing process. Ensure the ordering documentation matches the exact part number to avoid confusion with the MAX4607 or MAX4609 variants which have different internal switch configurations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual normally-open configuration is required within the MAX4607-09 family. Verify that the 2.5Ω on-resistance meets the signal integrity requirements for the specific application load. Ensure the operating voltage remains within the specified single or dual supply limits to maintain the guaranteed performance characteristics defined in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4607/MAX4608/MAX4609 series of dual analog switches manufactured by Analog Devices Inc./Maxim Integrated. While electrically similar regarding resistance and speed, the MAX4608 differs from the MAX4607 (two NC switches) and MAX4609 (one NC, one NO) by providing two normally open (NO) switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4608ESE+ is the lead-free/RoHS-compliant version of this component.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4608 and MAX4609?

The MAX4608 contains two normally open (NO) switches, whereas the MAX4609 contains one normally closed (NC) switch and one normally open (NO) switch.

How does the MAX4608 handle overvoltage conditions?

Signals exceeding V+ or V- are clamped by internal diodes. For protection, external blocking diodes can be added in series with the supply pins, though this reduces the usable analog signal range.

Is the MAX4608 compatible with TTL logic levels?

Yes, the digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS compatibility when using dual ±15V or a single +12V supply.
