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.
8. Measured using a 400 mV source, 50% duty cycle clock source. All output loading with external 50 W to VCC. Input edge rates 40 ps.
(20% 80%); PE = 0 dB, EQEN = 0
9. Input / Output voltage swing is a singleended measurement operating in differential mode.
10.VCMR min varies 1:1 with GND, VCMR max varies 1:1 with VCC. The VCMR range is referenced to the most positive side of the differential
input signal.
