DD
= 3.3V ± 5%, T
A
= -40°C to 85°C
NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when device
is mounted in a test socket with maintained transverse airflow greater than 500 lfpm. Device will meet specifications after thermal
equilibrium has been reached under these conditions.
NOTE 1: Measured from the differential input crossing point to the output at V
DD
/2.
NOTE 2: Defined as skew between outputs on different devices operating at the same supply voltage and with equal load conditions.
Using the same type of input on each device, the output is measured at V
DD
/2.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: This parameter is guaranteed by characterization. Not tested in production.
