Clock Generator Circuit for desktop video systems (CGC)

SAA7197

LIMITING VALUES

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

ground pins as well as supply pins together connected.

Note

1. Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is

recommended to take normal handling precautions appropriate to

“Handling MOS devices”.
