Description and Introduction

QUADRUPLE D-TYPE FLIP-FLOPS WITH CLEAR The SN74LS171N is a 4-bit D-type register with clear, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Register  
- **Number of Bits:** 4  
- **Output Type:** Standard  
- **Voltage Supply:** 4.75V to 5.25V  
- **Operating Temperature:** 0°C to 70°C  
- **Package/Case:** PDIP-16  
- **Mounting Type:** Through Hole  
- **Propagation Delay:** Typically 15ns  
- **High-Level Output Current:** -0.4mA  
- **Low-Level Output Current:** 8mA  

### **Descriptions:**  
The SN74LS171N is a 4-bit register with parallel inputs and outputs. It features a common clear input that resets all flip-flops to a low state when activated.  

### **Features:**  
- **Parallel Data Storage:** Stores 4 bits of data.  
- **Common Clear Input:** Resets all outputs to low.  
- **TTL-Compatible Inputs/Outputs:** Works with standard TTL logic levels.  
- **Wide Operating Voltage Range:** Supports 4.75V to 5.25V.  
- **High-Speed Operation:** Low propagation delay for efficient performance.  

This information is based solely on the device's technical specifications from TI.

Application Scenarios & Design Considerations

QUADRUPLE D-TYPE FLIP-FLOPS WITH CLEAR

Alternative Part Number

  • DM74LS171N --: Same 74LS171 quad D flip-flop function with clear, pin-compatible DIP-16 package from an alternate vendor.
  • MC74LS171N --: Direct functional equivalent 74LS171 device in DIP-16, suitable drop-in replacement with matching logic family.
  • SN74LS175N --: Quad D flip-flop in the same LS family and DIP-16 package; usable substitute if clear/preset configuration differences are acceptable.
  • 74LS171PC --: Equivalent 74LS171 quad D flip-flop in DIP package, same logic family and pinout, different series naming.
