Abstract:
1. A device comprising: input and output nodes; first and second input circuits coupled in parallel to each other between the input and output nodes, wherein the first input circuit comprises a first circuit unit coupled between the input and output nodes, the first circuit unit being configured to be activated when a first selection signal supplied thereto takes an active level and deactivated when the first selection signal takes an inactive level; and a control circuit configured to control the first and second input circuits such that one of the first and second input circuits is switched over from an active state to an inactive state and the other of the first and second input circuits is switched over from an inactive state to an active state during the one of the first and second input circuits being still in the active state; wherein the first input circuit is configured to respond to a change of a control signal from a first logic level to a second logic level and the first input circuit is configured to change the first selection signal from the active level to the inactive level after a lapse of a first period, and the first input circuit is configured to respond to a change of the control signal from the second logic level to the first logic level and change the first selection signal from the inactive level to the active level within a second period that is shorter than the first period.
