these circuits. If any external part constants are modified before use, factors such as variation in all external parts and
ROHM LSI ICs, including not only static characteristics but also transient characteristics, should be fully considered to set
an ample margin.
If the absolute maximum ratings for applied voltage and/or operation temperature are exceeded, LSI damage may result.
Therefore, do not apply voltage or use in a temperature that exceeds these absolute maximum ratings. If it is possible that
absolute maximum ratings will be exceeded, use a physical safety device such as a fuse and make sure that no conditions
that might exceed the absolute maximum ratings will be applied to the LSI IC.
Regardless of the operation mode, the voltage of the GND pin should be at least the minimum voltage. Actually check
whether or not the voltage at each pin, including transient phenomena, is less than the GND pin voltage.
The thermal design should be done using an ample margin that takes into consideration the allowable dissipation under
actual use conditions.
When mounting LSI ICs onto the circuit board, make sure each LSI's orientation and position is correct. The ICs may
become damaged if they are not mounted correctly when the power is turned on. Similarly, damage may also result if a
short occurs, such as when a foreign object is positioned between pins in an IC, or between a pin and a power supply or
GND connection.
When used within a strong electromagnetic field, evaluate carefully to avoid the risk of operation faults.

unused input pins should instead be connected to GND via a capacitor or else directly connected to VCC.

series resistors having resistance of several dozen
