SN54HC195 に関する概要
These 4-bit registers feature parallel inputs, parallel outputs, J-K serial inputs, shift/load control input, and a direct overriding clear. The registers have two modes of operation: parallel (broadside) load, and shift (in the direction QA and QD).
Parallel loading is accomplished by applying the 4-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 accomplished 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 T type flip-flop as shown in the function table.
The SN54HC195 is characterized for operation over the full military temperature range of –55°C to 125°C.
