13 LIMITING VALUES
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134); parameters are valid
over operating temperature range unless otherwise specified; all voltages referenced to V
SS
= 0 V. Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of
the device at these or at any other conditions above those given in the characteristics sections of the specification is not
implied. Exposure to limiting values for extended periods may affect device reliability.
14 HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices (see “Handling MOS Devices”).
