*Pb-free PDIPs can be used for through-hole wave solder
processing only. They are not intended for use in Reflow
solder processing applications.
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:
5. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
6. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air.
7. 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 for details.
8. For θJC, the “case temp” location is taken at the package top center.
9. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Test Conditions: VCC = 4.5V to 5.5V; Unless Otherwise Specified. Typicals are at VCC = 5V,
TA = +25°C (Note 10). Boldface limits apply over the operating temperature range,
-40°C to +85°C.
