Overview
The HCF4021YM013TR is a monolithic integrated circuit fabricated in metal oxide semiconductor technology, offered by STMicroelectronics. This device is an 8-stage parallel or serial-input/serial-output register, featuring 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 outputs available from stages 6, 7, and 8. The device is available in PDIP-16 and SO-16 packages, with the HCF4021YM013TR specifically being an automotive-grade SO-16 package.
