Functional description [1] H = HIGH voltage state; L = LOW voltage state; = LOW-to-HIGH transition; X = don’t care; NC = no change; Z = high-impedance OFF-state. Table 3. Function table[1] Control Input Output Function SHCP STCP OE MR DS Q7S Qn X X L L X L NC a LOW-level on MR only affects the shift registers X L L X L L empty shift register loaded into storage register X X H L X L Z shift register clear; parallel outputs in high-impedance OFF-state X L H H Q6S NC 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 Q6S) appears on the serial output (Q7S). X L H X NC QnS contents of shift register stages (internal QnS) are transferred to the storage register and parallel output stages L H X Q6S QnS contents of shift register shifted through; previous contents of the shift register is transferred to the storage register and the parallel output stages Fig 7.
