NOTES:
1. An unstabilized supply can be used; transients of 2 V allowed with max slope 0.1 V/µs.
2. All other inputs at 0V; all outputs at V_P and I_O = 0 µA.
3. Switching levels with respect to MOT1, MOT2 and MOT3.
4. Drivers are in high impedance OFF–state.
5. The outputs are short–circuit protected by limiting the current and the IC temperature.
