Description
Change in t_PD for different common mode voltages at the input pins.
Time skew between 50% levels of the rising edge of Q output and the falling
edge of Q output (Δt_PDLH), or time skew between 50% levels of falling edge
of Q output and rising edge of Q output (Δt_PDHL).
Average of t_PDLH and t_PDHL for L to H and H to L transients.
Average of t_PDHd and t_PDLd for L to H and H to L transients.
Time needed for the (single ended or differential) output voltage to change
from 20% of its nominal value to 80%.
Time needed for the (single ended or differential) output voltage to change

Comment
A This supply pin is independent of the supply for the input stage. This
allows output levels of different logic families.
A Output levels are determined by the choice of V_CCOA.
A Output levels are determined by the choice of V_CCOA.
A All four V_EE pins are circular connected together via two antiparallel
diodes. (See Figure 4)

B This supply pin is independent of the supply for the output stage.
V_CCIand V_CCO share the same ground pin V_EE.
B Input for analog voltages between 200 mV below V_EE and 2V below
V_CCI.
