The MM54HC195 MM74HC195 is a high speed 4-bit SHIFT REGISTER utilizes advanced silicon-gate CMOS technology to achieve the low power consumption and high noise immunity of standard CMOS integrated circuits along with the ability to drive 10 LS-TTL loads at LS type speeds This shift register features parallel inputs parallel outputs JK serial inputs SHIFT LOAD control input and a direct overriding CLEAR This shift register can operate in two modes PARALLEL LOAD SHIFT from QA towards QD Parallel loading is accomplished by applying the four bits of data and taking the SHIFT LOAD control 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 occurs synchronously when the SHIFT LOAD con-
