Section 19. Electrical Specifications
19.1 Introduction
This section contains electrical and timing specifications.
19.2 Absolute Maximum Ratings
Maximum ratings are the extreme limits to which the MCU can be exposed without
permanently damaging it.
NOTE:
This device is not guaranteed to operate properly at the maximum ratings. For
guaranteed operating conditions, refer to 19.5 DC Electrical Characteristics.

NOTE:
This device contains circuitry to protect the inputs against damage due to high
static voltages or electric fields; however, it is advised that normal precautions be
taken to avoid application of any voltage higher than maximum-rated voltages to
this high-impedance circuit. For proper operation, it is recommended that VIn and
VOut be constrained to the range VSS ≤ (VIn or VOut) ≤ VDD. Reliability of operation
is enhanced if unused inputs are connected to an appropriate logic voltage level
(for example, either VSS or VDD).
