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 lfpm. 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. LVPECL Outputs loaded with 50 W termination resistors to VTT = VCC – 2.0 V for proper operation.
5. LVPECL Output parameters vary 1:1 with VCC.
