NOTES: A. Pulse skew, t
sk(p)
, is defined as the difference in propagation-delay times t
PLH1
and t
PHL1
on the same terminal at identical
operating conditions.
B. Output skew, t
sk(o)
, is defined as the difference in propagation delay of any two outputs of the same device switching in the same
direction (e.g., |t
PLH1
– t
PLH2
|).
C. Temperature skew, t
sk(temp)
, is the output skew of two devices, both having the same value of V
CC
± 1% and with package
temperature differences of 20°C.
D. Load skew, t
sk(load)
, is measured with R
X
in Figure 2 at 13 W for one unit and 56 W for the other unit.
