Hello guys and sorry for my total newbiness.

I have just salvaged some stepper motors and their drivers. From my past experience, I drove the motors using a driver that had as logical inputs step, direction and enable. Those drivers that I salvaged(SLA7033) got 4 logical inputs, such as IN a, IN A, IN b, IN B.
Here is a link with drivers datasheet http://www.allegromicro.com/~/media/...eet.ashx?la=en..

Can someone tell me if it's possible to command this driver with step, direction and enable signals?

Regards,
Emanuel G
