CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1.
θ
JA
is measured with the component mounted on an evaluation PC board in free air.
2. All grounds (AGND, BGND) must be applied before V
CC
or V
BAT
. Failure to do so may result in premature failure of the part. If a user wishes
to run separate grounds off a line card, the AG must be applied first.

NOTES:
3. These parameters are controlled by design or process parameters and are not directly tested. These parameters are characterized upon initial
design release, upon design changes which would affect these characteristics, and at intervals to assure product quality and specification com-
pliance.
4. For transhybrid circuit as shown in Figure 10.
5. Application limitation based on maximum switch hook detect limit and metallic currents. Not a part limitation.
