Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74AHC374DWR is an octal edge-triggered D-type flip-flop with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology Family:** AHC  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Number of Channels:** 8  
- **Output Type:** 3-State  
- **Clock Frequency:** Up to 125 MHz (typical at 5 V)  
- **Propagation Delay:** 7.5 ns (max at 5 V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (DWR)  
- **Pin Count:** 20  
- **Logic Type:** D-Type Flip-Flop  
- **Input Type:** CMOS  
- **Output Current:** ±8 mA  

### **Descriptions:**  
The SN74AHC374DWR is a high-speed, low-power octal flip-flop with 3-state outputs. It is designed for bus-oriented applications and features edge-triggered D-type inputs and a buffered clock input. The outputs can be placed in a high-impedance state when not in use.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **High-Current 3-State Outputs:** Drive up to 8 mA  
- **Low Power Consumption:** Optimized for battery-operated devices  
- **Balanced Propagation Delays:** Ensures signal integrity  
- **ESD Protection:** Exceeds 2000 V per JESD 22  
- **Bus-Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors  
- **Latch-Up Performance:** Exceeds 250 mA per JESD 17  

This device is commonly used in data storage, bus interfacing, and signal buffering applications.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • MC74VHC374DWR2G --: Octal D-type flip-flop with 3-state outputs in the same SOIC-20 wide package, functionally equivalent to the SN74AHC374 with compatible AHC/VHC logic family.
  • 74AHC374D,118 --: Direct AHC-family octal D flip-flop with 3-state outputs in SOIC-20, matching logic function and supply voltage range.
  • 74VHC374MTCX --: VHC-family octal D-type flip-flop with 3-state outputs, pin-compatible and electrically similar, usable as a drop-in alternative.
  • SN74LV374ADWR --: Same manufacturer octal D-type flip-flop with 3-state outputs in SOIC-20, LV family provides comparable function with wider supply range and similar pinout.
