description/ordering information  
The ’AHC595 devices 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 registers. The shift  
register has a direct overriding clear (SRCLR)  
input, serial (SER) input, and a serial output for  
cascading. When the output-enable (OE) input is

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