CD4021 IC Serial-In Parallel-Out Shift Register DIP-16 CD4021

Product Overview

The CD4021B is an 8-stage static shift register that supports both parallel and serial input, with serial output. It features common CLOCK and PARALLEL/SERIAL CONTROL inputs, along with individual parallel "JAM" inputs for each stage. A key distinction of the CD4021B is that its serial entry is synchronous with the clock, while its parallel entry is asynchronous. The device is designed for medium-speed operation and utilizes CMOS technology, providing robust performance with standardized, symmetrical output characteristics.
