Hi,
What is preferred method to protect the MUX509 from damage caused by analog input voltage exceeding the MUX analog power supply voltage?
Does the MUX509 use internal ESD diodes to protect the inputs? If so, would a series current limit resistors + internal ESD diodes protect the device by clamping action?
Thanks,
Mark
Hi Mark,
Yes the MUX509 has internal ESD Diodes.
Here is a link to a very good app note on how to handle situations like what you have mentioned.
For future reference - you can find app notes and tech notes like this under the technical documents page of the product folder. :)
What is causing overvoltage events in your system?
