DATA OUTPUT APPARATUS OF SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PURPOSE: A data outputting device of a semiconductor integrated circuit is provided to improve a slow rate by including a predriver driving control unit. CONSTITUTION: A predriver outputs a driving control signal by receiving a data signal. A main driver(320) receives the driving control signal outputted from the predriver and outputs data. A predriver driving control unit(330) controls the driving of the predriver. A pull-up predriver(311) is driven by receiving a signal generated when a clock rises. A pull-down predriver(312) is driven with a signal generated when a clock falls.
