Abstract:
1. A circuit for driving a link being programmable by an energy pulse, the circuit generating an output signal with a boosted signal level compared with a logic level of an input signal, the circuit comprising: an input stage having a first input terminal pair for receiving a first input signal with a logic level, and a second input terminal pair for receiving a second input signal with a logic level, said input stage having a first switch pair with control inputs forming said first input terminal pair, said input stage having a second switch pair connected to said first switch pair for forming a logic combination of the first and second input signals, said second switch pair having control inputs forming said second input terminal pair; an output stage connected to said input stage and having a terminal for feeding in a blowing voltage, a first supply voltage terminal, and an output terminal coupled to the link and the output signal with the boosted signal level is tapped at said output terminal; and a switch having a control input and a controlled path with a first terminal connected to said terminal for feeding in the blowing voltage and a second terminal connected to the link, said control input of said switch connected to said output terminal of said output stage and, depending on the first and second input signals, said switch through-connects said first terminal of said controlled path, connected to said terminal for feeding in the blowing voltage, to said second terminal of said controlled path connected to the link.
