NOTE:
1. All voltages referenced to V

2. Typically the value of V
REF
is expect to be 0.5x V

Q of the transmitting device. V
REF
is expected to track variations in
V

.
*Stresses greater than those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only, and functional opera-
tion of the device at these or any other conditions above
those indicated in the operational sections of this speci-
fication is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliabil-
ity.
**Junction temperature depends upon package type,
cycle time, loading, ambient temperature, and airflow.
