◁
Electrical Characteristics
TA=-40°C to +85°C. Device meets the specifications after thermal equilibrium has been established when mounted in
a test socket or printed circuit board with maintained transverse airflow greater than 500lfpm. Electrical parameters
are guaranteed only over the declared operating temperature range. Functional operation of the device exceeding
these conditions is not implied. Device specification limit values are applied individually under normal operating
conditions and not valid simultaneously.
