L293D PowerDIP-16 Stepper Motor Controller/ Driver is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors.
The Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoids, DC and stepping motors) and switching power transistors. To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included.
It is suitable for use in switching applications at frequencies up to 5 kHz. The L293D is assembled in a 16 lead plastic package which has 4 centre pins connected together and used for heatsinking The L293DD is assembled in a 20 lead surface mount which has 8 centre pins connected together and used for heatsinking.
L293D contains two inbuilt H-bridge driver circuits. In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction. The motor operations of two motors can be controlled by input logic at pins 2 & 7 and 10 & 15. Input logic 00 or 11 will stop the corresponding motor. Logic 01 and 10 will rotate it in clockwise and anticlockwise directions, respectively. Enable pins 1 and 9 (corresponding to the two motors) must be high for motors to start operating.
When an enable input is high, the associated driver gets enabled. As a result, the outputs become active and work in phase with their inputs. Similarly, when the enable input is low, that driver is disabled, and their outputs are off and in the high-impedance state. They are designed to drive inductive loads such as relays, solenoids, dc and bipolar stepping motors, as well as their high-current/high-voltage loads in positive-supply applications.
If you want to control the dc motor with these motor driver ICs, for that you will need few essential components like

they function well every time.
Nice Stepper Motor Driver
all work and the price is ok.
used this H bridge to power up a small dc motor for an Arduino UNO project and it worked just fine
Used with Arduino UNO - just perfect
Smart choice
I was glad to get my hands on this motor driver IC that too at such affordable rate.
was satisfied by the quality, although it is a standalone IC not a module.
