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.

NOTE 1: This parameter is defined in accordance with JEDEC Standard 65.

NOTE 2: Defined as skew within a bank of outputs at the same supply voltage and with equal load conditions.

NOTE 3: Defined 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: Defined as the maximum instantaneous voltage including overshoot. See Parameter Measurement Information

Section.

NOTE 6: Defined 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: Defined 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.
