74HC595; 74HCT595  
8-bit serial-in, serial or parallel-out shift register with output  
latches; 3-state  
Rev. 6 — 12 December 2011  
Product data sheet  
1. General description  
The 74HC595; 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.
