Figure 15. Output–to–Output Skew tSK(LH, HL)
The pin-to-pin skew is defined as the worst case difference in
propagation delay between any similar delay path within a
single device
The time from the output controlled edge to the non-controlled
edge, divided by the time between output controlled edges,
expressed as a percentage
