Details
The HEF4021B is a CMOS 8-stage static shift register IC (Integrated Circuit). It features an 8-bit parallel-in/serial-out shift register with a storage latch and 3-state outputs. The IC operates at a voltage range of 3V to 15V, making it compatible with a wide range of applications.The HEF4021B has a clock input (CP) for shifting data through the register, a parallel data input (D) for loading data into the register, and a master reset input (MR) for clearing the register. It also has a serial output (Q7) for cascading multiple devices together.The IC is commonly used in applications such as LED displays, digit counters, and serial data transmission due to its simple operation and low power consumption. The HEF4021B is available in various package options including DIP (Dual Inline Package) and SOIC (Small Outline Integrated Circuit).
