Note:
Absolute maximum ratings
Stressing the device above the ratings listed in the “Absolute maximum ratings” tables may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to the conditions in this section for extended
periods may affect device reliability. Refer also to the STMicroelectronics SURE Program
and other relevant quality documents.

1. Current forced means voltage unlimited but current limited to the specified value voltage forced
means voltage limited to the specified values while the current is not limited
2. Typical value soldered on a PC board with 8 cm2 copper ground plane (35 mm thick).
The circuit is ESD protected according to MIL-STD-883C.
