Electrical characteristics
5.1
Absolute maximum ratings
This product contains devices to protect the inputs against damage due to high/low static
voltages. However it is advisable to take normal precaution to avoid application of any
voltage higher/lower than the specified maximum/minimum rated voltages.
The absolute maximum rating is the maximum stress that can be applied to a device without
causing permanent damage. However, extended exposure to minimum/maximum ratings
may affect long-term device reliability.
5.2
Maximum power consumption
Note:
These values take into consideration the worst cases of process variation and voltage range
and must be used to design the power supply section of the board.
