Description
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
