ABSOLUTE MAXIMUM RATINGS(1)

NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause

permanent damage to the device. This is a stress rating only and functional operation

of the device at these or any other conditions above those indicated in the operational

sections of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

2. All device terminals except FCT162XXX Output and I/O terminals.

3. Output and I/O terminals for FCT162XXX.
