              Application No. 09/124,091                                                                                  

                     9.     A multiplexer circuit comprising:                                                             
                            a first transistor coupled between a first predetermined voltage and                          
                     a node;                                                                                              
                            a second transistor coupled between a second predetermined                                    
                     voltage and the node; and                                                                            
                            a third transistor coupled between a third predetermined voltage                              
                     and the node, wherein said first, second and third transistors are                                   
                     responsive to first, second and third clock signals, respectively such that                          
                     one of the first, second and third predetermined voltages is outputted at                            
                     the node, the first, second and third predetermined voltages being                                   
                     different, and said first transistor is a mono-directional transistor and said                       
                     second transistor is a bi-directional transistor, and the second                                     
                     predetermined voltage is less than the first predetermined voltage, and                              
                     greater than the third predetermined voltage.                                                        

                     The prior art references of record relied upon by the examiner in rejecting the                      
              appealed claims are:                                                                                        
              Takahashi et al. (Takahashi)               4,551,634                    Nov. 05, 1985                       
              Appellant’s admitted prior art (AAPA) as shown in Figures 1A-1C and Figure 2A-2B                            
                     Claims 9-21 stand rejected under 35 U.S.C. § 103 as being unpatentable over                          
              Takahashi in view of AAPA.                                                                                  
                     Rather than reiterate the conflicting viewpoints advanced by the examiner and                        
              appellants regarding the above-noted rejections, we make reference to the examiner's                        
              answer (Paper No. 13, mailed Dec. 23, 1999) for the examiner's reasoning in support of                      
              the rejections, and to appellants’ brief (Paper No. 12, filed Oct. 20, 1999)  for                           
              appellants’ arguments thereagainst.
