600mA OUTPUT CURRENT CAPABILITY PER CHANNEL
1.2A PEAK OUTPUT CURRENT (non repetitive)PER CHANNEL
ENABLE FACILITY
OVERTEMPERATURE PROTECTION
LOGICAL "0" INPUT VOLTAGE UP TO 1.5 V(HIGH NOISE IMMUNITY)
INTERNAL CLAMP DIODES

The Device is a mnolithic integrated high voltage,high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, 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. This device is suitable for use in switching applications at frequencies up to 5 kHz.

Le code:
//L293D
//Motor A
const int motorPin1  = 5;  // Pin 14 of L293
const int motorPin2  = 6;  // Pin 10 of L293
//Motor B
const int motorPin3  = 10; // Pin  7 of L293
const int motorPin4  = 9;  // Pin  2 of L293

//This will run only one time.
void setup(){
 
    //Set pins as outputs
    pinMode(motorPin1, OUTPUT);
    pinMode(motorPin2, OUTPUT);
    pinMode(motorPin3, OUTPUT);
    pinMode(motorPin4, OUTPUT);
    
    //Motor Control - Motor A: motorPin1,motorpin2 & Motor B: motorpin3,motorpin4

    //This code  will turn Motor A clockwise for 2 sec.

    digitalWrite(motorPin2, LOW);
    digitalWrite(motorPin3, LOW);
