Caution
excess absolute maximum ratings, such supply voltage, temperature range operating conditions, etc., break down devices, thus making impossible identify breaking mode such short circuit open circuit. special mode exceeding absolute maximum ratings assumed, consideration should given take physical safety measures including fuses, etc.
Make setting potential terminal that will maintained minimum operating state.
short mistake fitting When mounting PCB, attention orientation there placement mistake, burned
noted that using strong electric field malfunction them.
