Description and Introduction

8-BIT PARALLEL-OUT SERIAL SHIFT REGISTERS The SN74HC164 is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to 85°C  
- **High-Level Input Voltage (Min):** 3.15V (at 4.5V supply)  
- **Low-Level Input Voltage (Max):** 1.35V (at 4.5V supply)  
- **Output Current (Max):** ±5.2mA (at 4.5V supply)  
- **Propagation Delay:** 14ns (typical at 5V supply)  
- **Package Options:** SOIC, PDIP, TSSOP  

### **Descriptions:**  
- The SN74HC164 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), and outputs are available in parallel.  
- A LOW on the reset pin (MR) clears all registers asynchronously.  

### **Features:**  
- **8-Bit Serial-In, Parallel-Out Shift Register**  
- **Gated (Enable/Disable) Serial Inputs**  
- **Asynchronous Master Reset**  
- **Buffered Clock and Serial Inputs**  
- **Wide Operating Voltage Range (2V to 6V)**  
- **Balanced Propagation Delays**  
- **High Noise Immunity**  
- **Low Power Consumption**  

This information is based on TI's official datasheet for the SN74HC164.

Application Scenarios & Design Considerations

8-BIT PARALLEL-OUT SERIAL SHIFT REGISTERS

Alternative Part Number

  • CD74HC164E --: Same 8-bit serial-in/parallel-out shift register function with HC speed grade, pin-compatible in DIP package and widely available.
  • MC74HC164AN --: Direct functional equivalent 8-bit shift register in HC logic family, pin-compatible and commonly used as a second source.
  • 74HC164N --: Standard 74HC series 8-bit serial-in/parallel-out shift register, pin-compatible and suitable as a lower-cost alternative.
