I've built a stepper motor circuit using an L293D chip which receives 4 inputs, A, B, C and D from three data latches. I'm measuring the voltage of A, B,C and D for each step of the motor and was wondering if the table below shows the correct pattern.
I'm using a 4.5v power supply and any help would be much appreciated.

but you should really dump that piece of garbage from ST (L293) - you are losing half your voltage in it (see the data sheet spec - saturation voltage)
