Precautions for Use
■ Correct Use
• The absolute maximum rating is the limit value which should not be
exceeded even in a flash. Exceeding this value can cause deterio-
ration of the characteristics or complete failure of the IC.
• Sufficiently take into consideration the static electricity, chattering
and voltage of the input to be connected when determining each
input terminal. Since unused input terminals may cause an
undefined state in the internal circuit, connect them to a power
supply (voltage = V_CC or less), like I/O.
• Although the device contains an ESD protection circuit, static elec-
tricity that exceeds the function may damage the device. When
handling the device, exercise due caution by, for example, ground-
ing the human body.
• Due to the structure of the IC, parasitic elements are formed
unavoidably. Exercise due caution not to use the device in a way
that activates the parasitic elements. For example, do not apply a
voltage lower than GND to the input terminals.
• Taking the power dissipation in actual use into consideration, per-
form thermal design with a sufficient margin. When a voltage
applied to the IC is high, which is due to, for example, a small num-
ber of LED’s driven in series, IC heat generation can be controlled
by inserting a resistance and spreading power consumption evenly.
• This IC incorporates a built-in thermal shutdown circuit. If the chip
temperature rises too high, this circuit works and the output termi-
nal becomes an open state. When the chip temperature returns to
a normal range, the output terminal also returns to its original state.
This circuit is a protective function for use at an emergency, so
please do not use it as a regular function.
• Due to potential damage, do not use product that has been
dropped or that has come into contact with water.
