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. Please refer to the Typical Application Schematics (page 3) for 3.3V/5V input configuration.
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.
Electrical Specifications
Recommended operating conditions unless otherwise noted. Refer to “Functional Block Diagram” on page 2
and Typical Application Schematic beginning on page 2. V CC = +3.3V. 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.
