All parameters measured at f_MAX unless noted otherwise.
NOTE 1: Measured from V_DD/2 of the input to V_DDO/2 of the output.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at V_DDO/2.
NOTE 3: Defined as the 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_DDO/2.
NOTE 4: These parameters are guaranteed by characterization. Not tested in production.
NOTE 5: This parameter is defined in accordance with JEDEC Standard 65.
