The most common ESD protection for I/Os consist of two diodes. To cover all the different stress combinations a rail clamp is required. In this article we discuss another option. For many interfaces a local ESD protection clamp is actually a better option.

3 problems with diode based ESD protection
The conventional dual diode approach is used a lot as a simple ESD protection solution for all types of interfaces. However sometimes it causes issues.
