Electrical characteristics
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.
Table 15.
Maximum power consumption
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.
