NOTE 1: This Table assumes the Top Driver Polarity Select (Pin 20) = Logic 0.
For Pin 20 = Logic 1, invert the polarity of the top drivers.
NOTE 2: For the LS7561N, the Overcurrent Sense = Logic 1 only forces the bottom drivers to a Logic 0.
It has no effect on the top driver outputs which are determined by the other inputs as shown in the table.
