ABSTRACT:
A semiconductor device includes a current-driven differential driver and a control circuit. The current-driven differential driver is configured to generate a pair of signals having levels relative to each other from a serial signal input therein and output a current from a current source included therein through an output node according to each of the signals. The control circuit controls the current-driven differential driver to pass the current from the current source as a throwaway current therein during a second predetermined time after an input of the serial signal stops and to block the throwaway current after the second predetermined time passes.
