NOTE: Electrical parameters are guaranteed over the specifi ed ambient operating temperature range, which is established
when the device is mounted in a test socket with maintained transverse airfl ow greater than 500 lfpm. The device will meet
specifi cations after thermal equilibrium has been reached under these conditions.
NOTE 1: Measured from the differential input crossing point to the differential output crossing point.
NOTE 2: Defi ned 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 the differential cross points.
NOTE 3: This parameter is defi ned in accordance with JEDEC Standard 65.
NOTE 4: Input duty cycle must be 50%.
