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. No terminal voltage may exceed

Vcc by +0.5V unless otherwise noted.

2. Inputs and Vcc terminals only.

3. Output and I/O terminals only.
