Parameters measured at f MAX unless otherwise noted.
NOTE 1: Measured from VDD /2 of the input to VDDO /2 of the output.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDDO /2.
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 VDDO /2.
NOTE 4: Defined from 20% to 80%
