This is a Quad Half H-Bridge, which can drive 2 motors up to 1A

Don't forget to add flyback diodes to the outputs as explained in the datasheet, you could use these 1N4001 diodes

The reason why you need an H-Bridge is that the motors are made of coils, and when current is switched ON and OFF on a coild, a very high voltage is generated (V = di/dt) which can destroy your H-Bridge, when you add the "flyback diodes" the danger to the chip is eliminated because all the current will "fly-back" to the power supply either through Vcc or GND
