ABSTRACT:
An output driving device capable of improving a slew rate is provided. The output driving device includes a push-pull type driving unit configured with a pull-up PMOS transistor and a pull-down NMOS transistor, wherein body biases of the pull-up PMOS transistor and the pull-down NMOS transistor are controlled for control of a slew rate of an output signal of the driving unit.
