Abstract

The invention relates to a driver circuit for binary signals, said circuit having two branch circuits which are connected in parallel with one another between an input node and an output node, the first of which branch circuits contains an output stage which, in response to the first binary value of a binary signal that is applied to the input node, connects the output node to a first logic potential via a first nonreactive resistor, and the second of which branch circuits contains an output stage which, in response to the second binary value of the binary signal that is applied to the input node, connects the output node to a second logic potential via a second nonreactive resistor. According to the invention, the driver circuit contains a duty ratio control device for setting the signal propagation time from the input node to the output stage of one branch circuit relative to the signal propagation time from the input node to the output stage of the other branch circuit.
