Overview
The CD4015BMT, produced by Texas Instruments, is a CMOS Dual 4-Stage Static Shift Register. This integrated circuit consists of two identical, independent 4-stage serial-input/parallel-output registers. Each register has independent CLOCK and RESET inputs, along with a single serial DATA input. The CD4015BMT is designed for medium speed operation and is fully static, making it suitable for a variety of digital logic applications. Although this product is no longer in production, it remains relevant for existing designs and educational purposes.
