(1)

A resistive divider with 2 × R1 between VCC and VSS is used as load. The output is connected to the center tap of the divider. For full

drive strength, R1 = 550

Ω. For reduced drive strength, R1 = 1.6 kΩ. CL = 20 pF is connected to the output to VSS.

(2)

The output voltage reaches at least 10% and 90% VCC at the specified toggle frequency.
