Abstract
A low voltage differential signaling driver includes at least one output circuit, a first control circuit, and a second control circuit. The output circuit includes a first input terminal to receive a first input signal, a second input terminal to receive a second input signal, a first output terminal to output a first output signal, a second output terminal to output a second output signal, and first to sixth transistors. The first control circuit controls a voltage of a control terminal of the first transistor to make a voltage of the first output signal equal to a first reference voltage when the first input signal has a first value. The second control circuit controls a voltage of a control terminal of the second transistor to make the voltage of the first output signal equal to a second reference voltage when the first input signal has a second value.
