DATASHEET L293B PDF

No, they are not fast diodes. I would use a BYV27 click! The L consists of 4 half bridges. The PDF shows multiple options in 1 schematic. You can create 2 full bridges with them, 4 half bridges or any combination you like. If you need to control 1 direction, you can do so with 1 half bridge.

As the name suggests it is mainly used to drive motors. A single LD IC is capable of running two DC motors at the same time; also the direction of these two motors can be controlled independently. So if you have motors which has operating voltage less than 36V and operating current less than mA, which are to be controlled by digital circuits like Op-Amp, timers , digital gates or even Micron rollers like Arduino, PIC, ARM etc.. The IC works on the principle of Half H-Bridge, let us not go too deep into what H-Bridge means, but for now just know that H bridge is a set up which is used to run motors both in clock wise and anti clockwise direction.

As said earlier this IC is capable of running two motors at the any direction at the same time, the circuit to achieve the same is shown below.

All the Ground pins should be grounded. The other is Vs Vcc2 which provides voltage for the motors to run, based on the specification of your motor you can connect this pin to anywhere between 4. The input pins Input 1,2 are used to control the motor 1 and Input pins 3,4 are used to control the Motor 2.

The input pins are connected to the any Digital circuit or microcontroller to control the speed and direction of the motor. You can toggle the input pins based on the following table to control your motor.
