MOUNTING INSTRUCTIONS
The R
of the L293B and the L293E can be reduced by soldering the GND pins to a suitable copper
th j-amb
area of the printed circuit board as shown in figure 12 or to an external heatsink (figure 13).
During soldering the pins temperature must not exceed 260°C and the soldering time must not be longer
than 12 seconds.
The external heatsink or printed circuit copper area must be connected to electrical ground.
