BGF148 protection equivalent, 7 line esd and emi interface protection.
* 7 line bidirectional ESD protection
* ESD protection according to IEC61000-4-2 for ±15 kV contact discharge on all external IOs
* ESD protection according .
due to low line capacitance of typical 1.2 pF
* Very low voltage dependency of line capacitance
* Very low leaka.
