Atmega168-PU 8-bit IC Microcontroller Previous 
The 74HC595 Shift Register is an 8-bit serial-in, serial or parallel-out device with a storage register and 3-state outputs. It is designed for expanding output pins in electronics, robotics, and Arduino projects. The device includes a serial input, a serial output for cascading, and separate clocks for the shift register and storage register. It also supports direct clear and output enable control for high-impedance operation. Inputs include clamp diodes for interfacing inputs to voltages above VCC with current limiting resistors.
