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.

3. Actual voltage levels and differential swing will depend on customer termination scheme. Typically, a 400mV swing is available in the 100

Ω environ-

ment and a 200mV swing in the 50

Ω environment. Refer to the “CML Termination” diagram for more details.
