74HC595 8-Bit Serial to Serial/Parallel IC DIP-16

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 chip’s 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!

Features

• It is a shift register with 8-bit serial input and 8-bit serial or 3-state parallel outputs.
• The operating voltage of this IC is from 2V to 6V.
• The output voltage is equal to the operating voltage of this IC.
• It is based on CMOS logic and therefore consumes a very low power of 80uA.
• The output source/sink current is 35mA.
• It has a characteristic of high noise immunity.
• It can be easily cascaded through pin 9 with more IC to get more outputs.
• The maximum clock frequency is 25Mhz @4.5V.
• Schmitt trigger action is provided on all inputs.
