Classification: H03K

Abstract:
A semiconductor device formed on a semiconductor substrate, comprising:an output terminal;a first MOS transistor responsive to activation of a first internal control signal for supplying current to said output terminal from a power supply;a first driving circuit responsive to the activation of said first internal control signal for outputting a second internal control signal having an activation potential higher than that of said first internal control signal;a second MOS transistor having its gate receiving said second internal control signal and responsive to activation of said second internal control signal for supplying current to said output terminal from said power supply;a second driving circuit responsive to the activation of said first internal control signal for outputting a third internal control signal having an activation potential higher than that of said second internal control circuit after the activation of said second internal control signal; anda third MOS transistor having its gate receiving said third internal control signal and responsive to activation of said third internal control signal for supplying current to said output terminal from said power supply.
