ELECTRICAL CHARACTERISTICS
1.
Absolute Maximum Ratings
(AV
SS
= V
SS
= 0.0 V)
Precautions: Permanent device damage may occur if the above “Absolute Maximum Ratings” are exceeded.
Functional operation should be restricted to the conditions as detailed in the operational sections of
this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
* :
Applicable to pins: P00 to P07, P20 to P23, AN0 to AN3
Use within recommended operating conditions.
Use at DC voltage (current).
The +B signal should always be applied with a limiting resistance placed between the +B signal and the
microcontroller.
The value of the limiting resistance should be set so that when the +B signal is applied the input current to
the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods.
