NOTES:
1. Device-to-Device Skew considering HIGH-to-HIGH transitions at common
VCC level.
2. Within-Device Skew considering HIGH-to-HIGH transitions at common
VCC level.
3. Within-Device Skew considering LOW-to-LOW transitions at common
VCC level.
4. All skew parameters are guaranteed but not tested.
5. Frequency at which output levels will meet a 0.8V to 2.0V minimum swing.
6. The fMAX value is specified as the minimum guaranteed maximum
frequency. Actual operational maximum frequency may be greater.
