DM54S195 DM74S195 4-Bit Parallel Access Shift Registers June 1989 DM54S195 DM74S195 4-Bit Parallel Access Shift Registers General Description These 4-bit registers feature parallel inputs parallel outputs J-K serial inputs shift load control input and a direct overriding clear All inputs are buffered to lower the input drive requirements The registers have two modes of operation Parallel (broadside) load Shift (in the direction QA toward QD) Parallel loading is acplished by applying the four bits of data and taking the shift load control input low The data is loaded into the associated flip-flop and appears at the outputs after the positive transition of the clock input During...
