4015 is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. 4015 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. The resetting of all stages is accomplished by a high level on the reset line. It is possible to expand the register to 8 stages using one 4015 package and to expand to more than 8 stages by using addition HCF4015Bs.
