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: This parameter is defi ned in accordance with JEDEC Standard 65.
NOTE 2: Defi ned as skew within a bank of outputs at the same supply voltage and with equal load conditions.
NOTE 3: Defi ned as skew between outputs at the same supply voltages and with equal load conditions.
Measured at V
DDOB, C
/2.
NOTE 4: Measurement taken from single-ended waveform.
NOTE 5: Defi ned as the maximum instantaneous voltage including overshoot. See Parameter Measurement Information
Section.
NOTE 6: Defi ned as the minimum instantaneous voltage including undershoot. See Parameter Measurement Information
Section.
NOTE 7: Measured at crossing point where the instantaneous voltage value of the rising edge of Qx equals the falling edge of
nQx. See Parameter Measurement Information Section.
NOTE 8: Refers to the total variation from the lowest crossing point to the highest, regardless of which edge is crossing. Re-
fers to all crossing points for this measurement. See Parameter Measurement Information Section.
NOTE 9: Defi ned as the total variation of all crossing voltage of rising Qx and falling nQx. This is the maximum allowed vari-
ance in the V
CROSS
for any particular system. See Parameter Measurement Information Section.
