AC Electrical Characteristics for ACTQ

Notes:

13. Voltage range 5.0 is 5.0V ± 0.5V.

14. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate

outputs of the same device. The specification applies to any outputs switching in the same direction, either
