This is a breakout board for 74HC595 8 bit Shift Register.The 74HCT595 are high-speed Si-gate CMOS devices and are pin 
compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A.The 74HC595; 
74HCT595 are 8-stage serial shift registers with a storage register and 3-state outputs. The registers have separate 
clocks.Data is shifted on the positive-going transitions of the shift register clock input (SHCP). The data in each 
register is transferred to the storage register on a positive-going transition of the storage register clock input (STCP). 
If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register.The 
shift register has a serial input (DS) and a serial standard output (Q7S) for cascading. It is also provided with 
asynchronous reset (active LOW) for all 8 shift register stages. The storage register has 8 parallel 3-state bus driver 
outputs. Data in the storage register appears at the output whenever the output enable input (OE) is LOW.
