Description: The MM54C195/MM74C195 CMOS 4-bit registers feature parallel inputs, parallel outputs, J-K serial input...
The MM54C195/MM74C195 CMOS 4-bit registers feature parallel inputs, parallel outputs, J-K serial inputs, shift/load control input and a direct overriding clear. The following two modes of operation are possible: Parallel Load Shift in direction QA towards QD Parallel loading is accomplished by applying the four bits of data and taking the shift/load control of input low.
The data is loaded into the associated flip-flops and appears at the outputs after the positive transition of the clock input. During parallel loading, serial data flow is inhibited.
Serial shifting is accomplished synchronously when the shift/load control input is high. Serial data for this mode is entered at the J-K inputs. These inputs allow the first stage to perform as a J-K, D, or T-type flip flop as shown in the truth table.
