Recommended Application Circuit
The values for the respective devices are all recommended values. For values under each input condition,
see the above-mentioned recommended operating conditions.
Note: Adding bypass capacitors is recommended.
Make sure that GND wiring has only one contact point, and to design the pattern that allows the heat
radiation.
To control setting pins in each mode by SW, make sure to pull down or pull up them to avoid high
impedance.
To input the data, see the section on the recommended input data.
The IC may be destroyed due to short circuit between output pins, an output pin and the V
DD
pin, or an
output pin and the GND pin.
Design an output line, V
DD
(V
M
) line and GND line with great care.
Also a low-withstand-voltage device may be destroyed when mounted in the wrong orientation, which
causes high-withstanding voltage to be applied to the device.
