Note: 1. Applying stresses in excess of the absolute maximum ratings may permanently damage the device. The values specified here are stress ratings only,
and do not refer to operation under conditions outside either these conditions or the operating conditions. Operating for extended periods at the
absolute maximum ratings may adversely influence device reliability. Unless otherwise specified, pin voltages must not exceed V
CC
+ 0.5 V.
2. All pins except the FCT162xxxT output and I/O pins
3. All FCT162xxxT output and I/O pins
