(1) A resistive divider with 2 × R1 between V
CC
and V
SS
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. C
L
= 20 pF is connected to the output to V
SS
.
(2) The output voltage reaches at least 10% and 90% V
CC
at the specified toggle frequency.
