CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Jedec Class II pulse conditions and failure criterion used. Level B exceptions are: Using a max positive pulse of 8.35V on all pins except X1 and
X2, Using a max positive pulse of 2.75V on X1 and X2, and using a max negative pulse of -1V for all pins.
2. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
DC Operating Specifications Unless otherwise noted, V_DD = +2.7V to +5.5V, T_A = -40°C to +85°C, Typical values are @ T_A = +25°C
and V_DD = 3.3V
