NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is
mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equilibrium
has been reached under these conditions.
All parameters measured at f_IN  250MHz unless noted otherwise.
NOTE 1: Measured from the V_DD/2 of the input to V_DDO/2 of the output.
NOTE 2: Defined as skew between outputs on different devices operating at the same supply voltage, same frequency, same temperature and
with equal load conditions. Using the same type of input on each device, the output is measured at V_DDO/2.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
