摘要：
A current driver circuit includes a pull-down switch unit that is coupled between a node and a first reference potential and is operative to switch between an on-state and an off-state responsive to an input signal. A pull-up switch unit is coupled between the node and a second reference potential and is operative to switch between an on-state and an off-state, complementary to the pull-down switch unit. A turn-on speed of the pull-up switch unit is slower than that of the pull-down switch unit, and a turn-off speed of the pull-up switch unit is faster than that of the pull-down switch unit.
