AC Electrical Characteristics

1

NOTE: 1. 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: 3. Measured from the differential input crossing point to the differential output crosspoint.

NOTE: 4. This parameter is defined in accordance with JEDEC standard 65.

NOTE: 5. Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the differential crosspoints.
