ABSTRACT:
In an output circuit for a signal transmission system to generate a bipolar output signal, a power output stage (62) is driven by a data signal and a transmitter release signal via an isolation stage (18) and a logic network (64). The power output stage comprises two complementary transistors whose bases are each separately driven from an output (50, 56) of the logic network (64) so that only one of the two transistors (54, 60) is switched to conducting in the presence of a transmitter release signal corresponding to the polarity of the output signal to be produced and so that both transistors (54, 60) are closed, independent of the data signal, in the absence of a transmitter release signal.
