For single-ended supplies, the driver outputs are
grounded.The VC terminal is switched to groundby
the totem-pole source transistors on alternate oscil-
lator cycles.

In conventional push-pull bipolar designs, forward
base drive is controlled by R1 - R3. Rapid turn-off
times for the power devices are achieved with
speed-up capacitors C1 and C2.
