NOTES:
1. Skew parameters are guaranteed across temperature range, but not tested. Skew parameters are measured at 0.5Vcc.
2. tSK(T) only applies to devices of the same transition, part type, temperature, power supply voltage, loading, package, and speed grade.

NOTES:
1. Minimums guaranteed but not production tested. Timing parameters are measured at 0.5Vcc.
2. The propagation delay other range indicated by Min. and Max. specifications results from process and environmental variables. These propagation
delays do not imply limit skew.
3. This parameter is guaranteed but not production tested.
