The ’HC595 contain an 8-bit serial-in, parallel-out  
shift register that feeds an 8-bit D-type storage  
register. The storage register has parallel 3-state  
outputs. Separate clocks are provided for both the  
shift and storage register. The shift register has a  
direct overriding clear (SRCLR) input, serial  
(SER) input, and serial outputs for cascading.

Both the shift register clock (RCLK) and storage  
register clock (SRCLK) are positive-edge trig-  
gered. If both clocks are connected together, the  
shift register is always one clock pulse ahead of  
the storage register.
