FUNCTION
a LOW level on MR only affects the shift registers
empty shift register loaded into storage register
shift register clear; parallel outputs in high-impedance
OFF-state
logic high level shifted into shift register stage 0;
contents of all shift register stages shifted through, e.g.
previous state of stage 6 (internal Q6’) appears on the
serial output (Q7’)
contents of shift register stages (internal Qn’) are
transferred to the storage register and parallel output
stages
contents of shift register shifted through; previous
contents of the shift register is transferred to the
storage register and the parallel output stages
