Classification: CPC H | IPC H

Claim 11:
12. An output driving circuit, comprising:
a pull-up circuit configured to cause an output voltage to transition from a low level to a high level based on connecting a power supply node to an output node in response to a pull-up signal;
a pull-down circuit configured to cause the output voltage to transition from the high level to the low level based on connecting a ground node to the output node in response to a pull-down signal;
a first bias voltage generating circuit configured to
provide a first bias voltage to the pull-up circuit and the pull-down circuit in response to the output voltage having a first type of transition, and
receive a parasitic current generated in the pull-up circuit and the pull-down circuit;

a second bias voltage generating circuit configured to
provide a second bias voltage to the pull-up circuit and the pull-down circuit in response to the output voltage having a second type of transition, and
provide a parasitic current to the pull-up circuit and the pull-down circuit; and

a switching control circuit configured to connect, according to a level of the output voltage, one of the first bias voltage generating circuit or the second bias voltage generating circuit to the pull-up circuit and the pull-down circuit.
