Notes:
1. For a chip mounted on a JEDEC 2S2P card without a heat sink.
2. For a chip mounted on a card with at least one signal and two power planes, the following relationships exist:
a. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board.
b. TA = TC – P×θCA, where TA is ambient temperature and P is power consumption.
c. TCMax = TJMax – P
×θ
JC, where TJMax is maximum junction temperature and P is power consumption.
Absolute Maximum Ratings
The absolute maximum ratings below are stress ratings only. Operation at or beyond these maximum ratings can cause
permanent damage to the device.
