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 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
