Usage Note : 1. Protective circuits must be inserted when using this IC with lines directly connecting the IC pins to external circuits.
(For example, this applies to pins 12 and 15.)
2. A 1000pF capacitor must be connected between either pin 5 and ground or between pin 5 and pin 8 to prevent VIF amplifier
oscillation.
