Features  
Description  
• Buffered Inputs  
The ’HC374, ’HCT374, ’HC574, and ’HCT574 are octal D-type  
flip-flops with 3-state outputs and the capability to drive 15  
• Common Three-State Output Enable Control

LSTTL loads. The eight edge-triggered flip-flops enter data into  
their registers on the LOW to HIGH transition of clock (CP). The  
output enable (OE) controls the 3-state outputs and is  
independent of the register operation. When OE is HIGH, the  
outputs are iin the high-impedance state. The 374 and 574 are  
identical in function and differ only in their pinout arrangements.
