The L293DNE Dual H-Bridge IC is able to run four solenoids, two DC motors or one bi-polar or uni-polar stepper motor, with up to 600mA per channel!
Each chip contains two full H-bridges (four half H-bridges) which means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. Just make sure they're good for under 600 mA since that's the limit of this chip. They do handle a peak of 1.2A but that's just for a short amount of time. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver
There's a PWM input per driver so you can control motor speed and the chip runs at 5V logic. Good for motor voltages from 4.5V up to 36V, and fits nicely in any breadboard or perfboard.
