Paul, I had the inputs all connected and outputs separate, each with a LED (3 total). I was going to drive 4 FETs from each driver.. Even without being hooked to the FETs, the LEDs would put on a light show. When I turn the throttle POT up and down,One might go out then another would dim. With the O-scope it shows it going into some super high frequency mess.. And this happens at the output only, Input is OK????? I tried changing the input resistors ,bigger and smaller, with no help..
The square wave suffers from only one driver, 12 FETs have quit a bit of capacitance..
