HD74LS195A
HD74LS195A is 4-bit Parallel-Access Shift Register manufactured by Renesas.
features 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 loading, serial data flow is inhibited. Shifting is acplished synchronously when the shift / load control input is high. Serial data for this mode is entered at the J-K inputs. These inputs permit the first stage to perform as a J-K, D-, or Ttype flip-flop as shown in the function table.
