Testing Procedure
- Connect the power supply source for input (VCC) and
the power supply for load (V Mot).
- Perform testing by giving a High logic (+5V) or Low
(0V) to the input (MIN1, MIN2, MEN1, MEN2, and
MPWM) that matches the truth table.
- Output terminals (MOUT1 and MOUT2) will produce
output voltage that matches the functions stated in the
truth table.
