Notes:

7. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.

8. Input and output parameters vary 1:1 with V

9. V

must be such that the peak-to-peak voltage is less than 1.0V and then greater than or equal to V

10. The differential propagation delay is defined as the delay from the crossing points of the differential input signals to the crossing point of the

differential output signals.

11. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal.

12. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device.

13. V

the E310L as a differential input as low as 50 mV will still produce full ECL levels at the output.
