ABSTRACT:
A signal switching circuit is provided to output signal switching between a first and a second input signal. The circuit includes a first analog switch transistor, a first switch transistor, a second analog switch transistor, a second switch transistor and a third switch transistor. The interference between the first input signal and the second input signal is reduced to a possible minimum through the invention.
