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.
NOTE:
1. 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.}
Electrical Specifications Operating Conditions: Vcc = 5V, T_A = -10^oC to 85^oC, Unless Otherwise Noted.
