4-BIT REGISTERS
General Description
The MM54C195 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.

"Absolute Maximum Ratings" are those values beyond which the safety of the device
cannot be guaranteed. Except for "Operating Temperature Range" they are not meant to
imply that the devices should be operated at these limits. The table of "Electrical
Characteristics" provides conditions for actual device operation.
