NOTES:
4.
胃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
胃JC, the 鈥渃ase temp鈥� location is taken at the package top center.
Electrical Specifications Test Conditions: VCC = 4.5V to 5.5V; Unless Otherwise Specified. Typicals are VCC = 5V, TA = +25掳C
(Note 6). Boldface limits apply over the operating temperature range, -40掳C to +85掳C.
