NOTES:
1. In applications where a motor is present, the input voltage may exceed the maximum V
I
, level of 10 V at the DIS input for a very short period
when the motor is switched off.
2. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those under “recommended operating conditions” is not implied. Exposure to absolute
maximum rated conditions for extended periods may affect device reliability.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
