Table 5B. AC Characteristics, V
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: Measured from the differential input crossing point to V
NOTE 2: Measured from V
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at V
NOTE 4: 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
NOTE 5: These parameters are guaranteed by characterization. Not tested in production.
NOTE 6: Setup and Hold times are relative to the rising edge of the input clock.
NOTE 7: This parameter is defined in accordance with JEDEC Standard 65.
