Abstract:
An integrated circuit, comprising:a terminal for supplying a digital signal; a controllable driver circuit having a driver input connected to said terminal for receiving the digital signal and a driver output for outputting the digital signal; an actuating circuit for actuating the driver circuit as a function of a clock signal, said actuating circuit having an actuating input for receiving the clock signal; and a comparator device having: a first comparator input for receiving the clock signal; a second comparator input connected to said driver output for receiving the digital signal; and a comparator output, said comparator device outputting, from said comparator output, an output signal having: a first state if a signal transition of the clock signal at said first comparator input takes place before a signal transition of the digital signal at said second comparator input; and a second state if the signal transition of the clock signal at said first comparator input takes place after the signal transition of said digital signal at said second comparator input.
