*Absolute maximum ratings are limiting values, to be applied individually, and

beyond which the serviceability of the circuit may be impaired. Functional

operability under any of these conditions is not necessarily implied. Exposure of

absolute maximum rating conditions for extended periods of time may affect

device reliability.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection.

Therefore, proper ESD precautions are recommended to avoid performance degradation or loss

of functionality.
