I would like to control the motor direction using an LM324(as a window comparator) & an L293D. the two output pins of my LM324 go to the Logic input pins of the L293D. The output voltage of the LM324 is 10.58V. According to the datasheet of the L293D the maximum input voltage to the logic pins should be less than equal to 7V. I cannot seem to understand the current requirements of the L293D using the datasheet. I wish to find the correct value of resistance wish is to be connected between the LM324 output pins to the input pins of the L293D.
