INTRODUCTION
The L293 is an integrated circuit motor driver that can be used for simultaneous, bidirectional
control of two small motors. Small means small. The L293 is limited to 600
mA, but in reality can only handle much small currents unless you have done some
serious heat sinking to keep the case temperature down. Unsure about whether the L293
will work with your motor? Hook up the circuit and run your motor while keeping your
finger on the chip. If it gets too hot to touch, you can't use it with your motor.
The L293 comes in a standard 16-pin, dual-in line integrated circuit package. For
complete information, consult the Unitrode L293 data sheet (PDF file, 626Kb).
The pinout for the L293 in the 16-pin package is shown below in top view. Pin 1 is at the
top left when the notch in the package faces up. Note that the names for pin functions
may be slightly different than what is shown in the following diagrams.
