Overview
The HEF4015BT, produced by Nexperia USA Inc., is a dual edge-triggered 4-bit static shift register that functions as a serial-to-parallel converter. This integrated circuit is part of the HEF4000 family and is designed for a wide range of applications due to its versatile features and robust specifications. Each shift register within the HEF4015BT has a serial data input (nD), a clock input (nCP), four fully buffered parallel outputs (Q0 to Q3), and an overriding asynchronous master reset input (nMR). This configuration allows for efficient data shifting and reset capabilities, making it suitable for various digital circuit designs.
