MAX4609ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4609ESE+ is a dual single-pole single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 2.5Ω. It operates from a single supply ranging from +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device includes one normally open and one normally closed switch, with rail-to-rail signal handling capabilities. Key electrical parameters include an on-resistance match of 0.5Ω max, off-leakage current of 2.5nA max at +85°C, turn-on time of 110ns, and turn-off time of 150ns. It is housed in a 16-pin Narrow SOIC package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the industrial temperature range (-40°C to +85°C) and 'SE' denotes the 16-pin Narrow SOIC package. Confirm the '+' suffix ensures RoHS compliance and lead-free status as per manufacturer specifications. Cross-reference the datasheet revision history to ensure all parameter limits are current before finalizing procurement documentation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4609ESE+ when a combination of one normally open and one normally closed SPST switch is required within a single package. Ensure the application signals remain within the specified rail-to-rail input voltage range relative to the chosen supply configuration. Verify that the 2.5Ω on-resistance meets the system's signal integrity requirements compared to higher resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4607/MAX4608/MAX4609 family of dual analog switches. While sharing identical electrical characteristics and pinouts, the MAX4609 differs by providing one normally open and one normally closed switch, whereas the MAX4607 offers two normally closed switches and the MAX4608 provides two normally open switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same package and specification include the MAX4607ESE+ and MAX4608ESE+. Note that these substitutes differ in switch polarity configuration: MAX4607ESE+ provides two normally closed switches, while MAX4608ESE+ provides two normally open switches.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4609 and the MAX4607?

Both devices share identical electrical specifications and pinouts. The primary difference lies in the switch configuration: the MAX4609 contains one normally open and one normally closed switch, while the MAX4607 contains two normally closed switches.

How does the MAX4609 handle overvoltage conditions?

Signals exceeding the supply rails are clamped by internal protection diodes. For proper operation without exceeding absolute maximum ratings, it is recommended to sequence power supplies correctly or add external blocking diodes if sequencing is not possible.

Is the MAX4609 compatible with standard logic families?

Yes, the digital inputs have +0.8V and +2.4V logic thresholds, ensuring compatibility with both TTL and CMOS logic levels when using appropriate supply voltages such as dual ±15V or single +12V.
