NOTES:
5. θJA 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.
6. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
7. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
8. For θJC, the “case temp” location is taken at the package top center.
Electrical Specifications - 2.7V to 5.25V Supply Test Conditions: VDD = +3.3V, GND = 0V, VLP = GND,
VOEH =1.4V, VOEL = 0.5V, (Note 9), Unless Otherwise Specified. Boldface limits apply over the operating temperature
range, -40°C to +85°C.
