Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 1. θJA 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 theta θJC the "case temp." location is the center of the exposed metal pad on the package underside. Electrical Specifications Typical values are tested at USB = CRDL = 5V and +25°C Ambient Temperature, maximum and minimum values are established over the recommended operating conditions, unless otherwise noted.
