The SN74HC595 is an 8-bit serial-in, parallel-out shift register designed for use in a wide range of digital applications. It is commonly used to expand the number of output pins available on microcontrollers and other digital devices. This shift register features a serial data input (DS), a clock input (SH_CP), a latch clock input (ST_CP), and an output enable input (OE). The SN74HC595 is ideal for driving LEDs, controlling displays, and other tasks requiring multiple output lines.
