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.
150°C max junction temperature is intended for short periods of time to prevent shortening the lifetime. Operation close to 150°C junction may trigger the shutdown of
the device even before 150°C, since this number is specified as typical.
NOTES:
1. θ_JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
2. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications VDD = 5V, TA = -10°C to +100°C, Unless Otherwise Specified.
