Notes:
1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is
not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng
conditions for extended periods may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.

Note:
1. The 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 transverse airflow of >500lfpm is maintained.

Notes:
1. Equilibrium temperature.
2. Inputs must be biased to logic LOW or HIGH when VCC is less than 3.0V.
3. Actual voltage levels and differential swing will depend on customer termination scheme. Typically, a 400mV swing is available in the 100
environ-
ment and a 200mV swing in the 50
environment. Refer to the “CML Termination” diagram for more details.
