DD
= 3.3V ± 0.3V, T
A
= -40°C to 85°C
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
MAX
unless noted otherwise.
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 inputs on each device, the outputs are measured at V
DD
/2.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
