CD4015B 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
CD4015B package, or to more than 8 stages using additional CD4015Bs is possible.
The CD4015B-series types are supplied in
16-lead hermetic dual-in-line ceramic
packages (F3A suffix), 16-lead dual-in-line
plastic package (E suffix), 16-lead
small-outline packages (M, M96, MT, and NSR
suffixes), and 16-lead thin shrink small-outline
packages (PW and PWR suffixes).
