This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. NOTES: 3. For VCC > 5.5V, current must be limited to 25mA. 4. 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. 5. Tolerance does not include the VID offset error or any external component tolerances. 6. For JC, the “case temp” location is the center of the exposed metal pad on the package underside. Electrical Specifications Operating Conditions: VCC = 5V, TA = -10°C to 100°C.
