Description and Introduction

8 BIT SIPO SHIFT REGISTER The M74HC164B1R is a high-speed CMOS 8-bit serial-in/parallel-out shift register manufactured by STMicroelectronics.  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +125°C  
- **High Noise Immunity:** Typical CMOS levels  
- **Low Power Consumption:**  
  - ICC (Static Current): 4 µA (max) at 5V  
- **High-Speed Operation:**  
  - Propagation Delay: 14 ns (typ) at 5V  
- **Output Current:** ±5.2 mA at 5V  
- **Package:** SO-14 (Small Outline)  

### **Descriptions:**  
- The M74HC164B1R is an 8-bit serial-in/parallel-out shift register with asynchronous reset.  
- Data is entered serially through one of two inputs (A or B), which are internally ANDed.  
- Outputs are available in parallel (Q0 to Q7).  
- A master reset (MR) pin clears all outputs when pulled low.  

### **Features:**  
- **Serial-to-Parallel Conversion:** Converts serial input data to parallel output.  
- **Dual Inputs (A & B):** Allows for flexible data entry.  
- **Asynchronous Reset (MR):** Clears all outputs when activated.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **Compatible with TTL Levels:** Inputs accept TTL signals.  
- **High-Speed Performance:** Suitable for fast digital applications.  

This information is based on the manufacturer's datasheet for the M74HC164B1R.
