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. Measured by forcing VINPP (MIN) from a 50% duty cycle clock source. All loading with an external RL = 50 W to VCC. Input edge rates 40 ps
(20% 80%).
5. Worstcase difference between QA0 and QA1 from either DA0 or DA1 (or between QB0 and QB1 from either DB0 or DB1 respectively),
when both outputs come from the same input.
6. Worstcase difference between QA and QB outputs, when DA or DB inputs are shorted.
7. Additive RMS jitter with 50% duty cycle input clock signal.
8. Additive peaktopeak data dependent jitter with input NRZ data signal.
9. Device to device skew is measured between outputs under identical transition @ 0.5 GHz.
10. LVTTL/LVCMOS input edge rate less than 1.5 ns
11. Data taken on the same device under identical condition.
