### **Descriptions:**  
- The SN74ALS574BNSR is a high-speed, octal D-type flip-flop with 3-state outputs.  
- It features a buffered common clock (CLK) and output enable (OE) inputs.  
- Data on the D inputs is transferred to the Q outputs on the positive edge of CLK.  
- The outputs are in a high-impedance state when OE is high.  

### **Features:**  
- **Edge-Triggered D-Type Inputs**  
- **3-State Bus Driving Outputs**  
- **Buffered Control Inputs**  
- **ESD Protection Exceeds 2000V per MIL-STD-883**  
- **Balanced Propagation Delays**  
- **Designed for High-Speed Memory Address Drivers**  

This device is commonly used in bus interface, register storage, and data buffering applications.
