Is it possible to use L293D without join it as a shield to arduino, but just send direction and speed by wires? If yes, which pin I need to use L293D?
Thank you!
I mean this shield
Applying 5V (connect to Vcc) or 0V (connect to GND) to the L293D inputs activates/deactivates the respective functions, as described in the L239D data sheet.
Use an Arduino PWM output to control motor speed.

thank you!
ups, I didn’t mention, I mean the shield from MH Electronics, like for 4 motors which can be connected to adruino directly
In that case, consult the data sheet for the shield as well as the L293D data sheet.

You can also get simple generic modules like this.

So I guess it will be easy to take the chip out from the board and use it as it is 
Yes, but I already have it, so will take out l293d chip and solder it
