AC ELECTRICAL CHARACTERISTICS
V
CC = 2.3V to 3.6V; GND = 0V; TA = –40°C to +85°C
(5)
Note 5.
Tested using environment of Figure 3, 50
equivalent load. AC parameters are guaranteed by design and characterization.
Note 6.
fMAX clock is defined as the maximum toggle rate the device can operate while still achieving a 250mV minimum CML output swing, 50
equivalent load.
Note 7.
Input TTL/CMOS edge rate of <1.5ns.
Note 8.
Worst-case difference between QA0 and QA1 from either DA0 or DA1 (or between QB0 and QB1 from either DB0 or DB1 respectively), when
both outputs come from the same input.
Note 9.
Worst-case difference between QA and QB outputs, when DA or DB inputs are shorted.

Note 3.
Device is guaranteed to meet the DC specifications, shown in the table above, after thermal equilibrium has been established. The device is
tested in a socket such that traverse airflow
≥500lfpm is maintained.
Note 4.
VOUT(SWING) is defined as the swing on one output of a differential pair, that is |VOH – VOL| on one pin. The swing for common mode immunity
purposes is 2
× V
OUT(SWING). Actual voltage levels and differential swing will depend on customer termination scheme. Typically, a 400mV
swing is available in the 50
environment. Refer to the “CML Output Termination Application” section, Figures 3 and 4, for more details.
