9.3.2 DC Motor Controls

Figure 9 and Figure 10 below depict a typical setup for using the L293 device as a controller for DC motors. Note

that the L293 device can be used as a simple driver for a motor to turn on and off in one direction, and can also

be used to drive a motor in both directions. Refer to the function tables below to understand unidirectional vs

bidirectional motor control. Refer to the Recommended Operating Conditions when considering the appropriate

input high and input low voltage levels to enable each channel of the device.

Connections to ground and to supply voltage
