CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
1. 250ns transient. See Confining The Negative Phase Node Voltage Swing in Application Information Section
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.
3. 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.
4. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
5. Limits established by characterization and are not production tested.
Electrical Specifications
Recommended Operating Conditions, Unless Otherwise Noted. Parameters with MIN and/or MAX limits are
100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are
not production tested.
