Notes:
-0.3V (-1.5V for <10ns) to 6.5V (7V for <10ns)
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
All Other Pins................................-0.3V to 6.5 V
Junction Temperature...............................150C
Lead Temperature ....................................260C
(2)
Continuous Power Dissipation (TA = +25°C)
