摘要：
An output driver includes: a pull-up signal generation unit configured to control a pulse width of first data and output a pull-up pre-drive signal; a pull-down signal generation unit configured to control a pulse width of second data and output a pull-down pre-drive signal; a pull-up pre-driver unit configured to receive the pull-up pre-drive signal and generate a pull-up main drive signal; a pull-down pre-driver unit configured to receive the pull-down pre-drive signal and generate a pull-down main drive signal; a pull-up main driver unit configured to charge an output node according to the pull-up main drive signal; and a pull-down main driver unit configured to discharge the output node according to the pull-down main drive signal.
