AC Electrical Characteristics for ACTQ
Note 16: Voltage Range 5.0 is 5.0V
Note 17: Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs within the same packaged device.
The specification applies to any outputs switching in the same direction, either HIGH-to-LOW (t
design. Not tested.
