Electrical Specifications
21.1 Introduction
This section contains electrical and timing specifications.
21.2 Absolute Maximum Ratings
Maximum ratings are the extreme limits to which the microcontroller unit (MCU) can be exposed without
permanently damaging it.
NOTE
This device is not guaranteed to operate properly at the maximum ratings.
Refer to 21.5 5.0-Vdc Electrical Characteristics for guaranteed operating
conditions.

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 V_In and V_Out be constrained to the range
V_SS ≤ (V_In or V_Out) ≤ V_DD. Reliability of operation is enhanced if unused
inputs are connected to an appropriate logic voltage level (for example,
either V_SS or V_DD).
