Note 1
The maximum junction temperature of the LM566CN is 150 C For operation at elevated junction temperatures maximum power dissipation must be
derated based on a thermal resistance of 115 CW junction to ambient
Applications Information
The LM566CN may be operated from either a single supply
as shown in this test circuit or from a split (g) power sup-
ply When operating from a split supply the square wave
output (pin 3) is TTL compatible (2 mA current sink) with the
addition of a 47 kX resistor from pin 3 to ground
A 0001 mF capacitor is connected between pins 5 and 6 to
prevent parasitic oscillations that may occur during VCO
switching
