pplications Information
The LM566CN may be operated from either a single supply as shown in this test circuit or from a split ( g ) power supply When operating from a split supply the square wave output (pin 3) is TTL compatible (2 mA current sink) with the addition of a 4 7 kX resistor from pin 3 to ground 0 001 mF capacitor is connected between pins 5 and 6 to prevent parasitic oscillations that may occur during VCO f switching
