(1)
All typical values are at 25°C and with a 3.3-V supply.
(2)
tsk(o) is the magnitude of the time difference between the tPLH or tPHL of all drivers of a single device with all of their inputs connected
together.
(3)
tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of any two devices characterized in
this data sheet when both devices operate with the same supply voltage, at the same temperature, and have the same test circuits.
