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
CC
. V
CC
can vary
±
0.3V.
9. V
is defined as the range within which the V
level may vary with the device still meeting the propagation delay specification. The V
IL
level
must be such that the peak-to-peak voltage is less than 1.0V and then greater than or equal to V
PP
(min).
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
(min) is defined as the minimum input differential voltage which will cause no increase in the propagation delay. The V
PP
(min) is AC limited for
the E310L as a differential input as low as 50 mV will still produce full ECL levels at the output.
