All parameters measured at fMAX unless noted otherwise.
NOTE 1: Measured from the 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 a the same supply voltage and with equal load conditions.
Using the same type of input on each device, the output is measured at VDDO/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.
