8-BIT SHIFT REGISTER WITH 8-BIT OUTPUT REGISTER  
Description  
Pin Assignments  
The 74HC594 is a high speed CMOS device.  
(Top View )  
An eight bit shift register accepts data from the serial input (DS) on  
each positive transition of the shift register clock (SHCP). When  
asserted low, the shift regisister reset function (SHR) sets all shift  
register values to zero and is independent of all clocks. Also when  
asserted low, the storage register reset function (STR) sets all shift  
register values to zero and is independent of all clocks.

Data from the input serial shift register is placed in the output register  
with a rising pulse on the storages resister clock (STCP). The  
storage resister includes output Q7S which is used for cascading  
information between devices. As the information moves into the  
storage register, it is asserted on the push-pull outputs Q0-Q7.

All registers capture data on rising edge and change output on the  
falling edge. If both clocks are connected together, the input shift  
register is always one clock cycle ahead of the output register.
