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 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, T A = -10°C to +100°C, 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.
