Abstract:
An output driving circuit may include a pull-up-pull-down driver connected to a pad, a level shifter operating based on a first power voltage and a second power voltage that is greater than the first power voltage, level shifting a data signal to generate a first control signal, and applying the first control signal to the pull-up-pull-down driver, and a driver control logic operating based on the first power voltage, generating a second control signal based on the data signal, and applying the second control signal to the pull-up-pull-down driver.
