Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. IO absolute maximum rating must be observed.
2. The package thermal impedance is calculated in accordance with JESD51−7.
3. 500 mW at 65
°C; derate to 300 mW by 10 mW/ from 65°C to 85°C.
4. Tested to EIA/JESD22−A114−A.
5. Tested to EIA/JESD22−A115−A.
6. Tested to JESD22−C101−A.
7. Tested to EIA/JESD78.
