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:

5. For up to 4 outputs per device, add

±25mA for each additional output.

6. Unless otherwise specified, all voltages are referenced to ground.

7.

θJA is measured with the component mounted on an evaluation PC board in free air.
