Description and Introduction

Serial-In Parallel-Out Shift Register The SN74LS164ML1 is a 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Shift Register  
- **Output Type:** Standard  
- **Number of Bits:** 8  
- **Function:** Serial to Parallel  
- **Voltage Supply:** 4.75V to 5.25V  
- **Operating Temperature:** -55°C to 125°C  
- **Package / Case:** SOIC-14  
- **Mounting Type:** Surface Mount  
- **Logic Family:** LS  
- **Propagation Delay Time:** 45 ns (typical)  
- **High-Level Output Current:** -0.4 mA  
- **Low-Level Output Current:** 8 mA  

### **Descriptions:**  
The SN74LS164ML1 is a high-speed 8-bit serial-in, parallel-out shift register. It features two serial data inputs (A and B) that are ANDed together, allowing flexible data entry. Data is shifted on the rising edge of the clock (CP) input. A master reset (MR) clears all flip-flops asynchronously.  

### **Features:**  
- **8-bit parallel output**  
- **Gated serial data inputs (A and B)**  
- **Asynchronous master reset**  
- **Wide operating voltage range (4.75V–5.25V)**  
- **Low power consumption (LS technology)**  
- **High-speed operation (45 ns typical propagation delay)**  
- **Surface-mount SOIC-14 package**  

This device is commonly used in applications requiring serial-to-parallel data conversion, such as LED displays, data storage, and digital signal processing.

Application Scenarios & Design Considerations

Serial-In Parallel-Out Shift Register

Alternative Part Number

  • CD74HC164E --: 8-bit serial-in/parallel-out shift register with the same function and pinout, CMOS HC family offers lower power and wider supply range than LS.
  • MC74HC164AN --: Direct functional equivalent 8-bit SIPO shift register in HC logic, widely available and pin-compatible with the 74LS164.
  • SN74HC164N --: Same TI shift register function in the HC series, drop-in compatible with improved power consumption and similar drive characteristics.
  • DM74LS164N --: Same 8-bit serial-in/parallel-out shift register function in the 74LS family, widely available and pin-compatible in DIP packages.
  • 74LS164 --: Direct functional equivalent 8-bit serial-in/parallel-out shift register from the original 74LS logic family, with broad availability.
  • MC74LS164N --: Equivalent 74LS164 shift register from a major logic supplier, suitable as a drop-in replacement for the original Motorola part.
