Description and Introduction

16-BIT SHIFT REGISTERS The SN74LS673N is a 16-bit serial-in, parallel-out shift register with output storage registers, manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Bits:** 16  
- **Input Type:** Serial  
- **Output Type:** Parallel  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP (Plastic Dual In-Line Package)  
- **Pin Count:** 24  
- **Clock Frequency:** Up to 25 MHz (typical)  
- **Propagation Delay:** 30 ns (max)  

### **Description:**  
The SN74LS673N is designed for serial-to-parallel data conversion. It features a serial input, parallel outputs, and internal storage registers that hold the shifted data until updated. It is commonly used in digital systems for data buffering, signal processing, and control applications.  

### **Features:**  
- **16-bit shift register with storage capability**  
- **Three-state outputs for bus-oriented applications**  
- **Asynchronous master reset for clearing registers**  
- **Schottky-clamped for high-speed operation**  
- **Low power consumption (typical ICC = 24 mA)**  
- **Wide operating voltage range (4.75V to 5.25V)**  

This information is based solely on the technical specifications of the SN74LS673N from Texas Instruments.

Application Scenarios & Design Considerations

16-BIT SHIFT REGISTERS

Alternative Part Number

  • DM74LS673N --: Same 74LS673 function (8-bit shift register with output latch) in a 24-pin DIP, pin-compatible with the TI device.
  • SN74LS674N --: Same LS family 16-bit shift register in a 24-pin DIP; functionally similar serial/parallel shift register, though bit width differs, so verify the application.
  • CD74HC673E --: CMOS 8-bit shift register with output latch in a 24-pin DIP; pin-compatible alternative when higher speed is not required, but check supply voltage and drive levels.
  • 74LS673N --: Standard 74LS673 shift register in DIP package, functionally and pin compatible with SN74LS673N.
  • MC74LS673N --: Second-source 74LS673 shift register in 24-pin DIP, direct functional replacement for the original part.
