Stresses above those hereby listed may cause damage to the device. The ratings are stress related only and functional operation of the device

at conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to maximum rating conditions for

extended periods may affect device reliability. Standard MOS circuits handling procedure should be used to avoid possible damage to the

device.
