Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Either or both input voltages should not exceed the magnitude of V or V
.
CC
EE
2. Power dissipation must be considered to ensure maximum junction temperature (T ) is not exceeded.
J
3. When driving inductive loads, negative flyback voltage/current excursions may need to be constrained with Schottky diodes to protect the
output drivers.
