t
SK3
is the difference in propagation delay times between any channels of any devices. This specification (maximum limit) applies to
devices within V
CC
±0.1V of one another, and a Delta T
A
= ±5°C (between devices) within the operating temperature range. This
parameter is guaranteed by design and characterization.
t
SK1
is the |t
PHL
– t

| of a channel.
t
SK2
is the maximum skew between any two channels within a device, either edge.
All channels switching, Output Duty Cycle criteria is 40%/60% measured at 50%. Input = 1V to 2V, 50% Duty Cycle, t
