14.4.2 Design Guidelines for 3.3V LV Diode
============================================
The following design guidelines are recommended for 3.3V LV N+/PWELL diode for good ESD protection.
14.4.2.1 Minimum cathode junction width (DL) is 0.36 um. Recommended two rows of contact in the cathode side
14.4.2.2 Recommended maximum cathode finger width (DW) is 40um.
