Inputs: “H” means that the input 1 potential for the corresponding phase is at least 0.2V higher than the input
2 potential.
“L” means that the input 1 potential for the corresponding phase is at least 0.2V lower than the input
2 potential.
Forward/reverse control: “H”: 1.6V to VCC2
“L”: 0V to 0.4 V
