Overview
TECHNICAL DATA IW4015B Dual 4-Stage Static Shift Register The IW4015B 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 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 IW4015B package, or to more than 8 stages using additional IW4015B’s is possible.
