Parameters measured at f_MAX unless otherwise noted.
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 /2.
DDO
NOTE 3: 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_DDO/2.
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
