† All typical values are at 25°C and with a 3.3-V supply.
‡ tsk(p) is the magnitude of the time difference between the high-to-low and low-to-high propagation delay times at an output
‡ tsk(o) is the magnitude of the time difference between the outputs of a single device with all of their inputs connected together.
‡ tsk(o) is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both devices operate
with the same supply voltages, same temperature, and have identical packages and test circuits.
