74595 IC 8-Bit Serial to Serial/Parallel

From the shop's description

Description The 74HC595 is a?very?handy IC used in many microcontroller projects. You clock in 8 bits of data (like, on/off settings for 8 LEDs) via two lines, and when you toggle a third line, it pops these settings out on 8 outputs on the IC. So you trade 3 valuable lines on your microcontroller for 8 outputs ? a pretty good deal, eh? This is called ?Shifting data out? of the microcontroller by ?synchronous serial communication?. This is the serial part of the deal, where each bit is ?shifted in? one at a time, then BOOM, they all appear at once (in?parallel)?on the chips output. There are some great tutorials on how to use a shift register.?Here?s one?for the Arduino microcontroller, but the technique holds true for pretty much all microcontrollers! Here?s the basic specifications: 8-bit Logic Family : HC Logical Function : Shift Register Operating Supply Voltage (Typ) : 5V Output Type : 3-State Package Type : DIP Propagation Delay Time : 265ns Operating Temp Range : -40C to 125C Operating Supply Voltage (Min) : 2V Operating Supply Voltage (Max) : 6V
