A.1.7 Operating Conditions
This section describes the operating conditions of the device. Unless otherwise noted these conditions
apply to the following electrical parameters.
NOTE
Please refer to the temperature rating of the device with regards to the
ambient temperature T
A
and the junction temperature T
J
. For power
dissipation calculations refer to Section A.1.8, “Power Dissipation and
Thermal Characteristics” .
NOTE
Operation is guaranteed when powering down until low voltage reset
assertion.
