PIN DESCRIPTIONS
ABSOLUTE MAXIMUM RATINGS
Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent dam-
age 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.
