74HC594; 74HCT594  
8-bit shift register with output register  
Rev. 7 — 20 October 2022  
Product data sheet  
1. General description  
The 74HC594; 74HCT594 is an 8-bit serial-in/serial or parallel-out shift register with a storage  
register. Separate clock and reset inputs are provided on both shift and storage registers. The  
device features a serial input (DS) and a serial output (Q7S) to enable cascading. Data is shifted  
on the LOW-to-HIGH transitions of the SHCP input, and the data in the shift register is transferred  
to the storage register on a LOW-to-HIGH transition of the STCP input. If both clocks are  
connected together, the shift register will always be one clock pulse ahead of the storage register.  
A LOW level on one of the two register reset pins (SHR and STR) will clear the corresponding  
register. Inputs include clamp diodes. This enables the use of current limiting resistors to interface  
inputs to voltages in excess of VCC  
.
2. Features and benefits
