Overview
The CD4015B, manufactured by Texas Instruments, is a CMOS Dual 4-Stage Static Shift Register. This component 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. The registers are designed with D-type, master-slave flip-flops, allowing for the logic level present at the DATA input to be transferred into the first register stage and shifted over one stage at each positive-going clock transition. The CD4015B is suitable for various applications requiring serial-to-parallel data conversion and general-purpose register functions.
