The SN74HC595N is an 8-bit shift register with output latches and three-state parallel outputs. This versatile IC (integrated circuit) is designed for use in a variety of serial-to-parallel and parallel-to-serial data storage and retrieval applications. The SN74HC595N features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. It also enables serial-in shift-left and shift-right operations, and parallel-loading (by using the flip-flops). This 16-pin IC has a wide operating voltage range of 2V to 6V, making it suitable for use in a range of electronic circuits and projects. The SN74HC595N is commonly used for driving LEDs, controlling multiple segments of a larger display, and expanding the number of outputs from a microcontroller. Its straightforward pinout and compatibility with a wide range of microcontrollers make it a popular choice for hobbyists and professionals alike.
