NOTES:
1. CLK skew is only valid for equal loading of all outputs.
2. TH is measured at 0.5 VDD as shown in Figure 2.
3. TL is measured at 0.35 VDD as shown in Figure 2.
4. TR and TF are measured as a transition through the threshold region 0.2 VDD to 0.6 VDD and 0.6 VDD to 0.2 VDD.
5. Input edge rate for these tests must be faster than 1 V/ns.
6. All typical values are at VCC = 3.3 V and Tamb = 25 °C.
