### **Description:**  
The SN74LV374ANSR features eight edge-triggered D-type flip-flops with 3-state outputs. It is designed for 2-V to 5.5-V VCC operation, making it suitable for interfacing between different voltage levels. The device has a buffered clock input and output enable (OE) control, allowing for efficient data storage and transfer.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **3-State Outputs for Bus Interface**  
- **Supports Mixed-Mode Voltage Operation**  
- **High-Current Outputs (±12 mA at 3.3 V)**  
- **Low Power Consumption (ICC = 20 µA max)**  
- **ESD Protection Exceeds JESD 22 (2000-V Human-Body Model, 200-V Machine Model)**  
- **Latch-Up Performance Exceeds 250 mA per JESD 17**  

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

Application Scenarios & Design Considerations

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs

Alternative Part Number

  • MC74LCX374DTR2G --: Octal D-type flip-flop with 3-state outputs in the same wide-body SOIC-20 package, functionally equivalent to the SN74LV374A and widely available as a drop-in replacement.
  • 74LVC374ADB --: Low-voltage CMOS octal D flip-flop with 3-state outputs, similar 2.0-3.6V operating range and pin-compatible logic function, suitable when a different package footprint can be accommodated.
  • SN74LVC374APWR --: Same TI LVC family logic function with 3-state octal D flip-flop, offering comparable speed and drive characteristics as an in-family alternative when the TSSOP package is acceptable.
  • MC74LVX374ADTR2G --: Octal D-type flip-flop with 3-state outputs in the same LVX logic family, similar 5V-tolerant inputs and speed, available in TSSOP-like package; a direct functional replacement.
  • 74LVC374APW --: Octal D-type flip-flop with 3-state outputs in LVC family, comparable low-voltage operation and drive strength, widely available in TSSOP package.
