None of the inputs to U1 or U2 of the DRF1300 are isolated for direct connection to a ground referenced power

supply or control circuitry. Isolation appropriate to the application is the responsibility of the end user.

It is imperative that high output currents be restricted to the Source (14, 16, 18) and drain (15, 17) pins by

design. See DRF100 for more information on Driver IC used in the device.

The Function (FN, pin 3 or pin 9) is the invert or non-invert select Pin, it is Internally held high.
