Description

CD4015BMS consists of two identical, independent, 4-stage

serial-input/parallel output registers. Each register has inde-

pendent 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, mas-

ter-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 pack-
