CD4015BMS consists of two identical, independent, 4-stage serial-input/parallel output registers. Each register has independent CLOCK and RESET inputs as well as a single serial DATA input. Q outputs are available from each of the four stages on both registers. All register stages are D type, master-slave flip-flops. The logic level present at the DATA input is transferred into the first register stage and shifted over one stage at each positive-going clock transition. Resetting of all stages is accomplished by a high level on the reset line. Register expansion to 8 stages using one CD4015BMS package, or to more than 8 stages using additional CD4015BMS's is possible. The CD4015BMS is supplied in these 16 lead outline packages: Braze Seal DIP H4X Frit Seal DIP H1F Ceramic Flatpack H6W
