Pin 14; B
This pin serves for limiting the base voltage of the internal output-stage transistors. If this pin
is connected to V
across Q2 (or Q4) and ground (watch out for power dissipation!).
Pin 15; C
A capacitor on this pin delays the activation of the outputs after the supply voltage is applied
(turn-ON delay). In this way erroneous pulses are prevented on the output during buildup of
the oscillator.
If V
this also being determined by C
is suppressed if there are just short glitches (voltage dips) on V
for large core diameters, because in such cases a relativity long turn-ON delay has to be
selected and the delayed twin-on operation would otherwise be activated each time there was
a brief voltage dip.
