10 LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
11 HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take precautions appropriate to handling MOS devices Advice can be found in Data Handbook IC12 under
“Handling MOS Devices”.
