For q to be adequate use ohm's law and crack open a few electronc books,
instead of bothering us with lazy answers.
The L293 only has a maximum output current of 600mA and he needs 700mA.
I don't know, since he only needs one, it might be possible to parallel two channels to increase the current rating. All the transistors are on the same die so should be well matched and be at the same temperature so current sharing should be pretty good.
