MM54C195/MM74C195 4-Bit Registers
General Description
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 Q
A
towards Q
D
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.
