Have just realized that the output driver chip (UNL2803A)that comes with the standard 18 pin project board inverts the output. Does anyone know of an equivalent chip (with same pinout) that does not invert?
I plan to use this board to drive four power MOSFETS in a H-bridge circuit so, with inverted outputs there will be a short circuit in the H-bridge for a short time on power up or reset i.e. all the MOSFETS will be on until the program can set the PIC outputs high.
