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.

6. Input VIL and VIH parameters vary 1:1 with VCC. Output VOH and VOL parameters vary 1:1 with GND.

7. The propagation delay is measured from the crosspoint of the input signal and the threshold value to the crosspoint of the Q and Q output

signals. For propagation delay measurements the threshold level (VTHR) is centered about an 850 mV input logic swing with a slew rate of

0.75 V/NS. There is an insignificant change in the propagation delay over the input common mode range.

8. tskew is the propagation delay skew between comparator A and comparator B for a particular part under identical input conditions.

9. Refer to Figure 4 and note that the input is at 850 mV ECL levels with the input threshold range between the 20% and 80% points. The delay

is measured from the crosspoint of the input signal and the threshold value to the crosspoint of the Q and Q output signals.

10.The slew rate is 0.25 V/NS for input rising edges.

11. The slew rate is 0.75 V/NS for input rising edges.

12.Refer to Figure 5 and note that the input is at 2.5 V TTL levels with the input threshold range between the 20% and 80% points. The delay

is measured from the crosspoint of the input signal and the threshold value to the crosspoint of the Q and Q output signals.

13.The slew rate is 0.3 V/NS for input rising edges.
