SL4015B

The SL4015B consists of two identical, independent, 4-stage serialinput/ parallel-output registers. Each register has independent CLOCK and RESET inputs as well as a single serial DATA input. "Q" outputs of the SL4015B 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 SL4015B package, or to more than 8 stages using additional SL4015B's is possible.
