Note 2: The collector of each transistor is isolated from the substrate by an integral diode. Therefore, the collector voltage should remain positive with respect to pin 17 at all times. Note 3: If oscillation exists under some load conditions, add 2.7X and 0.05 mF series network from pin 1 to ground. 2
