4. IC usage notes
Maximum ratings
When maximum ratings are surpassed, destruction or deterioration may result. Use the IC in the range where the
maximum rating is not exceeded.
Interpin short circuits and reverse insertions
These cause destruction or deterioration of the IC : be careful when mounting on circuit board.
Voltage applied to pin 8 should never exceed pin 9 voltage.
The current flowing into pin 8 is to be 0.5mA maximum.
Pin 4 is unconnected, but is not to be used for GND or an interconnecting terminal.
Note : IC = 600mA continuous is within 3 seconds
IC = 300mA continuous is within 30 seconds
IC = 100mA or less can be left on at all times.
