OUTPUT ENABLE CIRCUIT AND PROCESS FOR MULTIPLEXING DATA

PROBLEM TO BE SOLVED: To provide fast output enable path and method for an integrated circuit device which effectively minimizes gate delay in the data of a critical integrated circuit device and a clock path. SOLUTION: Several 'single shot' internal output enable clocks are generated on the basis of an external clock. Selection information is included in the parallel output enable clocks and makes it easy to multiplex some different data paths into a single output buffer. The selection information is realized at the reset part of a single shot circuit so as to be eliminated from a critical part for deciding access time.
