74HC595
The 74HC595 is an 8-bit serial-in/parallel-out shift register with an integrated storage register (latch) and three-state outputs. It belongs to the 74HC family of high-speed CMOS logic devices and is commonly used to expand microcontroller I/O without increasing the number of I/O pins.
Key features and pins include: DS for serial data input; SH_CP as the shift register clock input;
Operation generally involves shifting data into the device on the rising edge of SH_CP, with each bit
Electrical characteristics typically include a supply voltage range from 2 to 6 volts (with 4.5 to 5.5
Applications include expanding I/O for microcontrollers, LED and display drivers, and simple daisy-chained shift-register-based solutions for
