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. 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.
2. All voltages are relative to GND, unless otherwise specified.
3. Limits should be considered typical and are not production tested.
Electrical Specifications
V_DD = 12V, T_A = T_J = full temperature range, Unless Otherwise Specified.
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.
