$begingroup$There 7408 is used to drive Mosfets (I have IRFZ44n instead of TIP122). Its input is limited to 5.25V (not so much high volt to drive mosfets).
I want to provide higher volt pulse to Mosfet-Gate to make Mosfets turn-on fully. Is it really better idea to do this?
So I want to use L293 instead of 7408. Is it suitable to use.
Is it better to use co-amplifier (single-741, Dual-LM833, Quad-LM3900) instead of 7408?

Unipolar and bipolar driver architectures are most commonly used for stepper motors. Unipolar stepper motor indicates the stepper motor with 2 coils and 5 or 6 lines. That is, one tap is increased in the middle of one coil. 5 lines can be seen as 6 ones. The two intermediate line of two coils can be connected.
OR is there any other better option.

$begingroup$Maria popescu md. 5V logic is not nearly enough to turn on those MOSFETs sufficiently. Vgs threshold has a max value of 4V, so they may be barely on with a TTL high signal. 10V or 12V on the gate would be much better.
