Overview
The HCF4021M013TR is a monolithic integrated circuit fabricated in metal oxide semiconductor technology, designed and manufactured by STMicroelectronics. This device is an 8-stage static shift register that can operate in both asynchronous parallel input and synchronous serial-in/serial-out modes. It is available in PDIP-16 and SO-16 packages, making it versatile for various applications. The HCF4021 features common clock and parallel/serial control inputs, a single serial data input, and individual parallel 'jam' inputs to each register stage. Each register stage is a D-type, master-slave flip-flop, with buffered outputs available from stages 6, 7, and 8.
