NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 Ifpm. 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.
4. Measurement taken with outputs terminated with 100 ohm across differential pair. See Figure
5.5. Parameter guarantees 10 years of aging. Includes initial stability at 25°C, shock, vibration and first year aging.
