NOTES: A. Pulse skew, tsk(p), is defined as the difference in propagation-delay times tPLH1 and tPHL1 on the same terminal at identical

operating conditions.

B. Output skew, tsk(o), is defined as the difference in propagation delay of any two outputs of the same device switching in the same

direction (e.g., |tPLH1 – tPLH2|).

C. Temperature skew, tsk(temp), is the output skew of two devices, both having the same value of VCC ± 1% and with package

temperature differences of 20

°C.

D. Load skew, tsk(load), is measured with RX in Figure 2 at 13 W for one unit and 56 W for the other unit.
