NOTE 1: All parameters measured at f_MAX unless noted otherwise.
NOTE 2: Measured from V_DD/2 of the input to V_DDx/2 of the output.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at V_DDx/2.
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 5: Defined as skew between outputs on different devices operating at the same supply voltages and with equal load conditions. Using
the same type of inputs on each device, the outputs are measured at V_DDx/2.
