HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, it is good practice to take

normal precautions appropriate to handling MOS devices (see

“Data Handbook ICO3, Section: General, Handling MOS

devices”).

10 LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).
