NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-

INGS 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

3. Outputs and I/O terminals only.
