Abstract
A crosstalk-resistant multi-input to single output analog switching device is provided to prevent an appearance of a unwanted input signal at an output stage when any one of a diverse switches is selected in particular electronic and or electric products attached thereto. The analog switching device has an additional provision of a second reference voltage source and a second selective switch unit, thereby avoiding crosstalk generation by electrically blocking a signal transfer path between a selected input port and a non-selected input port. Furthermore, upon selectively turning on and off transistor switches, a pulse noise resulting form a change in bias voltage can be eradicated.
