ABSTRACT:
Each of first and second differential amplifiers has a function of increasing a bias current in response to the activation of a drivability control signal. A first driving circuit connects an output node to a high power supply line in response to the activation of an output signal of the first differential amplifier, and connects the output node to a low power supply line in response to the activation of an output signal of the second differential amplifier. Only during the activation period of the drivability control signal, a second driving circuit connects the output node to the high power supply line in response to the activation of the output signal of the first differential amplifier, and connects the output node to the low power supply line in response to the activation of the output signal of the second differential amplifier.
