Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
3. Power dissipation must be considered to ensure maximum junction temperature (T
J
) is not exceeded.

The maximum power that can be safely dissipated is limited
by the associated rise in junction temperature. For the plastic
packages, the maximum safe junction temperature is 150°C.
If the maximum is exceeded momentarily, proper circuit
operation will be restored as soon as the die temperature is
reduced. Leaving the device in the “overheated’’ condition for
an extended period can result in device damage.
