Description and Introduction

SERIAL-IN PARALLEL-OUT SHIFT REGISTER The SN74LS164N is a 8-bit serial-in/parallel-out shift register manufactured by **MOT (Motorola Semiconductor)**.  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Bits:** 8  
- **Logic Type:** Serial-In, Parallel-Out  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** PDIP-14 (Plastic Dual In-Line Package)  
- **Propagation Delay (Typical):** 20ns  
- **Output Current (High/Low):** -0.4mA / 8mA  
- **Power Dissipation (Max):** 80mW  

### **Description:**  
The SN74LS164N is a high-speed 8-bit serial-in/parallel-out shift register. It accepts serial data input and provides parallel output, making it useful for data expansion, serial-to-parallel conversion, and digital signal processing applications.  

### **Features:**  
- **8-bit serial-in/parallel-out operation**  
- **Gated (active-low) serial inputs for controlled data entry**  
- **Asynchronous Master Reset (MR) to clear all flip-flops**  
- **Compatible with TTL (Transistor-Transistor Logic) inputs**  
- **Low power consumption (typical LS family characteristics)**  
- **Wide operating voltage range (4.75V to 5.25V)**  

This device is commonly used in digital circuits requiring serial data expansion, LED driving, or interfacing with microcontrollers.

Application Scenarios & Design Considerations

SERIAL-IN PARALLEL-OUT SHIFT REGISTER

Alternative Part Number

  • DM74LS164N --: Same 8-bit serial-in/parallel-out shift register function with identical LS TTL logic and DIP-14 pinout, direct functional drop-in replacement.
  • 74LS164N --: Standard 74LS164 shift register in DIP-14 package, electrically and functionally equivalent to the original SN74LS164N.
  • MC74LS164N --: Motorola's 74LS164 8-bit shift register, same logic family and pinout, suitable as an equivalent substitute.
