NOTE 1: Switching characteristics over recommended ranges of supply voltages and operating free-air temperature,
C_L = 10pF, V_DD = 3.3V ± 0.3V.
NOTE 2: Measured from V_DD/2 of the input to V_DD/2 of the output.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at V_DD/2.
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 5: Defined as skew between outputs on different devices operating a the same supply voltages and
with equal load conditions. Using the same type of input on each device, the output is measured at V_DD/2.
