(1) All typical values are at 25 ° C and with a 3.3-V supply.
(2) t
sk(p)
is the magnitude of the time difference between the t
PLH
and t
PHL
of any output of a single device.
(3) t
sk(o)
is the magnitude of the time difference between the t
PLH
or t
PHL
of any outputs with both inputs tied together.
(4) t
sk(b)
is the magnitude of the time difference between the t
PLH
and t
PHL
of the two outputs of any bank of a single device.
(5) t
sk(pp)
is the magnitude of the time difference in propagation delay times between any specified terminals of two devices when both
devices operate with the same supply voltages, at the same temperature, and have identical packages and test circuits.
