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. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

2. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.

Electrical Specifications

Operating Conditions: VDD = 5V, TA = -40°C to +100°C, unless otherwise noted. 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.
