Abstract:
A line driver circuit for providing a complementary output signal on a first output line and a direct output signal on a second output line in response to an input signal, the line driver circuit comprising:an input line operable to receive and conduct the input signal;a first inverter having first and second input terminals and an output terminal coupled to the first output line, the first input terminal being connected directly to the input line of the line driver circuit;a second inverter having an output node coupled to the second output line;a third inverter having first and second input terminals and an output terminal coupled to an input node of the second inverter, the first input terminal of the third inverter being connected directly to the input line of the line driver circuit;a pass gate having first and second input terminals and an output terminal, the second input terminal being coupled to the input line of the line driver circuit, the output terminal of the pass gate being coupled to the second input terminal of the first inverter and the second input terminal of the third inverter, the pass gate being operable to receive an enable signal at the first input terminal, and operable to provide a conduction path between the input line of the line driver circuit and the output terminal of the pass gate in response to a first state of the enable signal;wherein the first and third inverters are each operable to invert the input signal to generate an output signal in response to the pass gate providing a conduction path between the input line of the line driver circuit and the output terminal of the pass gate, and wherein the second inverter is operable to invert the output signal of the third inverter to generate the direct output signal.
