Note 1. Operating Supply Voltage Range: VCC(opr) = 4.5V to 5.5V
Note 2. Pin8 shall be always used in connection with Pin23
Note 3. Power supply to be supplied to the variable resistor added to Pin2 and Pin17 shall be used
the same as that supplied to this integrated circuit.
Note 4. Since deterioration or destroy of characteristics due to flow of overcurrent caused by reverse
current, careful should be taken to handling.
