Description and Introduction

4-Bit D-type Registers with 3-State Outputs The SN54173J is a quad D-type flip-flop with clear, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 4  
- **Input Type:** Single-Ended  
- **Output Type:** Push-Pull  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package / Case:** CDIP-16 (Ceramic Dual In-Line Package)  
- **Mounting Type:** Through Hole  
- **Propagation Delay Time:** Typically 40ns (varies with conditions)  
- **High-Level Output Current:** -3mA  
- **Low-Level Output Current:** 24mA  

### **Descriptions and Features:**  
- Contains four independent D-type flip-flops with common clock and clear inputs.  
- Buffered outputs provide high drive capability.  
- Direct clear input resets all flip-flops asynchronously.  
- Compatible with most TTL logic families.  
- Designed for high-speed, low-power operation.  
- Military-grade reliability (indicated by "SN541" prefix).  

This device is part of TI's 5400 series, which is characterized by ruggedness and extended temperature range for military applications.

Application Scenarios & Design Considerations

4-Bit D-type Registers with 3-State Outputs

Alternative Part Number

  • DM74LS173AN --: Functionally equivalent 4-bit D flip-flop with 3-state outputs in a DIP package, widely available and pin-compatible.
  • MC74LS173AN --: Same 74LS173 logic function from a different manufacturer, offering a direct second-source option for the DIP package.
  • SN74LS173AN --: Commercial-temperature 74LS173 version from TI with identical logic function and pinout, suitable when military temperature range is not required.
  • DM74173N --: Same 4-bit D-type register function in a standard DIP package, widely available and pin-compatible in most designs.
  • 74LS173PC --: Low-power Schottky equivalent of the 4-bit register with tri-state outputs, direct functional replacement.
  • MC74173L --: Pin-compatible 4-bit D register from an alternate vendor, suitable when the original military-grade part is unavailable.
