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. This device is suitable for use in switching applications at frequencies up to 5 kHz. The L293D is assembled in a 16 lead plastic package that has 4 center pins connected together and used for heatsinking.

L293D Equivalent Dual Timer IC

LB1909MC, SN754410, ULN2003

Connections with Arduino

Module 5V (VCC) – Arduino 5V.
Module GND – Arduino GND.
Module 1 – Arduino D8.
Module 2 – Arduino D9.
Module 3 – Arduino D10.
Module 4 – Arduino D11.
Module Motor terminals – DC motors.
Module VSS power terminal- External power source of 9V.

Make the connection as shown above.

Make sure that the Jumpers are preset on the Enable 1-2 and Enable 3-4 pins of module, so that motor will be enabled and work at maximum speed.

2.1. Working Mechanism

Rotation of motor depends on Enable Pins. When Enable 1/2 is HIGH , motor connected to left part of IC will rotate according to following manner:

Input 1	Input 2	Result
0	0	Stop
0	1	Anti Clockwise
1	0	Clockwise
1	1	Stop
