A vacuum fluorescent display driving circuit is disclosed. The vacuum fluorescent display driving circuit is used for driving a vacuum fluorescent display to avoid unusual displaying caused by coupling of the vacuum fluorescent display. The vacuum fluorescent display driving circuit includes a first output pin set and a second output pin set. The first output pin set includes a plurality of first output pins and each of them includes two metal oxide semiconductor transistors, the second output pin set includes a plurality of second output pins and each of them includes a metal oxide semiconductor transistor and a resistor. No coupling effect will take place when the first output pin set and the second output pin set operate in the vacuum fluorescent display driving circuit.
