Abstract:
An output driver circuit of an integrated circuit, comprising:an input terminal for receiving an input signal; at least one output terminal for outputting an output signal; and a multiplicity of driver stages each having a driver circuit and a driver activation configuration outputting an activation signal for activating said driver circuit; each said driver activation configuration having a first input and a second input respectively activated in dependence on a changeover signal; said driver activation configurations being cascaded in series with a first driver activation configuration and a last driver activation configuration, wherein, proceeding from said first driver activation configuration, the activation signal of each said driver activation configuration is fed to said first input of each subsequent said driver activation configuration and, proceeding from said last driver activation configuration, the output signal of each said driver activation configuration is fed to said second input of each preceding said driver activation configuration; a control device connected to and transmitting the changeover signal to each driver activation configuration via a changeover line; an input line connected to said control device, said first input of said first driver activation configuration and said second input of said last driver activation configuration being connected to said control device via said input line, said input line carrying a delayed input signal by comparison with said input terminal; and said control device changing over between said first and second inputs of each said driver activation configuration.
