Data Sheet
November 2001
L9218A/G Low-Cost Line Interface
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. Some of the known examples of conditions that cause such potentials during powerup are the following:
1. An inductor connected to tip and ring can force an overvoltage on V
BAT
through the protection devices if the V
BAT
connection chatters.
2. Inductance in the V
BAT
lead could resonate with the V
BAT
filter capacitor to cause a destructive overvoltage.
