Latch Up (Tested per JESD-78A)
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:
4. 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.
5. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications These specifications apply for T A = -40°C to +105°C, unless otherwise stated. All typical specifications
T A = +25°C, VCC = 5V. Boldface limits apply over the operating temperature range, -40°C to +105°C.
