Additional preview pages of the U208B datasheet.

The integrated circuit, U208B, is designed as a phase control circuit in bipolar technology with internal supply-voltage monitoring.

As the voltage is built up, uncontrolled output pulses are avoided by internal monitoring.

Furthermore, it has internal-current and voltage synchronisation.
