Difference between L293 and L293D Motor Driver ICs

by realfinetime  |  in L293D at  22:55

L293 and L293D are popular motor driver ICs having a wide supply voltage range of 4.5V - 36V and is capable of handling an output current of 1A per channel. Pinout diagram of L293 and L293D is given below.

Main difference between L293 and L293D is , D in L293D indicates an internally fitted diode ( Output Clamp Diodes ) meaning that we don't need to add any external components. But if you are using L293 external diode has to be added. This diode is used for Inductive Transient Suppression.

IMPORTANT NOTICE

All the circuits, published in this blog is only after testing and getting proper results in my private lab. When you try these circuits, you should check the supply voltage, polarity of components, presence of childrens nearby and shorts in the circuits. This website will not be responsible for any harm happened to you or your components caused by your carelessness.
