ABSTRACT:
A liquid crystal driver circuit is arranged to select one of a plurality of different reference voltages in response to externally input through the effect of a multiplexer circuit. The liquid crystal driver further provides a buffer circuit at an output stage of the multiplexer circuit, arranged in a manner that its impedance is high at an input and low at an output to thereby lower an output impedance of the liquid crystal driver circuit.
