when using them. When modifying externally attached component constants before use, determine them so that they
have sufficient margins by taking into account variations in externally attached components and the Rohm LSI, not only for
static characteristics but also including transient characteristics.
Operating or testing the device over the maximum specifications may damage the part itself as well as peripheral
components. Therefore, please ensure that the specifications are not exceeded.
Ensure that the GND terminal is at the lowest potential under all operating conditions.
Use a thermal design that allows for a sufficient margin regarding power dissipation (Pd) under actual operating conditions.]
Incorrect orientation or misalignment of the IC when mounting to the PCB may damage part. Short-circuits caused by the
introduction of foreign matter between the output terminals or across the output and power supply or GND may also result
in destruction.
Operation in a strong electromagnetic field may cause malfunction.
Set the power source voltage so that VCC ≧ VDD.
The power on reset circuit, which initializes internal settings, may malfunction during abrupt power ons. Therefore, set
the time constant so as to satisfy the power source rise time.
