Description and Introduction

8−Bit Serial−Input/Parallel−Output Shift Register # **MC74HC164ADR2G: A High-Performance 8-Bit Serial-In/Parallel-Out Shift Register**  

In the world of digital electronics, efficient data handling is crucial for seamless system performance. The **MC74HC164ADR2G** from ON Semiconductor is a high-speed, low-power **8-bit serial-in/parallel-out shift register** designed to meet the demands of modern digital applications. Built using advanced silicon-gate CMOS technology, this component offers reliable operation, high noise immunity, and compatibility with standard CMOS and TTL logic levels.  

## **Key Features and Benefits**  

### **1. High-Speed Data Transfer**  
The MC74HC164ADR2G operates at **high clock frequencies**, making it ideal for applications requiring rapid serial-to-parallel data conversion. With a typical propagation delay of **13 ns**, it ensures swift data processing while maintaining signal integrity.  

### **2. Low Power Consumption**  
Thanks to its CMOS construction, this shift register consumes minimal power, making it a suitable choice for **battery-powered and energy-efficient devices**. Its low static and dynamic power dissipation enhances system longevity and reduces operational costs.  

### **3. Wide Operating Voltage Range**  
The device supports a **2V to 6V supply voltage range**, providing flexibility in various digital circuits. This feature allows seamless integration into both **3.3V and 5V systems**, ensuring broad compatibility across different platforms.  

### **4. Serial Input with Parallel Output**  
The MC74HC164ADR2G accepts **serial data input** and converts it into **8-bit parallel output**, simplifying data expansion in microcontroller-based systems. Its two serial input pins (A and B) can be tied together for single-input operation or used independently for added control.  

### **5. Robust Noise Immunity**  
With **high noise immunity** (up to 30% of the supply voltage), this shift register maintains stable performance even in electrically noisy environments, reducing the risk of data corruption.  

## **Applications**  
The MC74HC164ADR2G is widely used in applications requiring serial-to-parallel data conversion, including:  
- **LED matrix displays** (for driving multiple LEDs with minimal I/O pins)  
- **Data storage and retrieval systems**  
- **Serial communication interfaces**  
- **Industrial control systems**  
- **Automotive electronics**  

## **Reliability and Packaging**  
Available in a **SOIC-14 package**, the MC74HC164ADR2G is designed for **surface-mount assembly**, ensuring compact and efficient PCB integration. Its robust construction and adherence to industry standards guarantee long-term reliability in demanding environments.  

## **Conclusion**  
For engineers and designers seeking a **high-speed, low-power shift register** with excellent noise immunity and broad voltage compatibility, the **MC74HC164ADR2G** is a compelling choice. Its ability to efficiently manage serial-to-parallel data conversion makes it indispensable in digital systems where precision and performance are paramount.  

Whether used in display drivers, communication modules, or embedded control systems, this component delivers consistent, high-quality performance, reinforcing its reputation as a trusted solution in digital logic applications.

Application Scenarios & Design Considerations

8−Bit Serial−Input/Parallel−Output Shift Register

Alternative Part Number

  • SN74HC164DR --: Same 8-bit serial-in/parallel-out shift register function with identical HC logic family and pinout, widely available from a different manufacturer and series.
  • CD74HC164E --: Harris/Intersil-origin CD74HC164 series offers the same HC shift register functionality and pin compatibility, providing a distinct naming series as an alternative.
  • 74HC164D,653 --: Nexperia 74HC164 in SOIC package matches the logic function, supply range, and pinout, giving a second-source option with a clearly different part naming scheme.
