Abstract
A data output circuit for a semiconductor integrated circuit device for outputting a data signal in sync with an output enable signal externally supplied, including: a comparing circuit for comparing a first data signal being outputted presently with a second data signal to be outputted next, when the data signal to be outputted is changed, and judging whether the first and second data signals are the same or different; a first output circuit for temporarily turning off output transistors and outputting the second data, if the comparing circuit judges that the first and second data signals are different; and a second output circuit for outputting the second data signal without turning off all the output transistors, if the comparing circuit judges that the first and second data signals are the same.
