4 Electrical specification
The limiting values given are in accordance with the Absolute Maximum Rating System
(IEC 134). Stress above one or more of the limiting values may cause permanent damage
to the device. These are stress ratings only. Operation of the device at these or at any other
conditions above those given below is not implied. Exposure to limiting values for extended
periods may affect device reliability.
Where application information is given, it is advisory only and does not form part of the
specification.

Table 9: Absolute maximum ratings
The product is not protected against overvoltage or reversed voltages. Voltage spikes
exceeding the power supply voltage specification, given in the table above, must be limited
to values within the specified boundaries by using appropriate protection diodes.
4.2 Operating conditions
All specifications are at an ambient temperature of 25 °C. Extreme operating temperatures
can significantly impact the specification values. Applications operating near the
temperature limits should be tested to ensure the specification.
