Attention: Stresses above the max. values listed here may cause permanent damage to the device.
Exposure to absolute maximum rating conditions for extended periods may aect device reliability.
Maximum ratings are absolute ratings; exceeding only one of these values may cause irreversible damage
to the integrated circuit.
