74HC595 - eight-bit shift register with serial input, serial or parallel data output from the latch and tri-state output.
Also available as 74HC595D (SMD) - If you need the SMD version, please let us know.
A shift register allows you to expand the number of pins you can use from your Arduino (or any micro controller for that matter) by using what is known as bit-shifting.
This shift register will provide us with a total of eight extra pins to use (five if you subtract the three pins we need to connect to the Arduino from the shift register itself).
This item is available in stock and is not drop shipped. This avoids delays, customs charges and extra VAT.
