Preliminary Data Sheet
October 2001
Low-Cost Ringing SLIC
L9214A/G

Agere Systems Inc.
Absolute Maximum Ratings
(at T
A
= 25
°
C)
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Note: The IC can be damaged unless all ground connections are applied before, and removed after, all other connections. Furthermore, when
powering the device, the user must guarantee that no external potential creates a voltage on any pin of the device that exceeds the
device ratings. For example, inductance in a supply lead could resonate with the supply filter capacitor to cause a destructive overvoltage.
Table 3. Typical Operating Characteristics
Table 4. Thermal Characteristics
1. This parameter is not tested in production. It is guaranteed by design and device characterization.
2. Airflow, PCB board layers, and other factors can greatly affect this parameter.
