Description and Introduction

Serial-in shift registers The SN74LS164J is a shift register manufactured by Texas Instruments (TIX).  

### **Specifications:**  
- **Logic Type:** 8-Bit Serial-In, Parallel-Out Shift Register  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** 14-Pin DIP (Dual In-Line Package)  
- **Output Type:** Standard (TTL-Compatible)  
- **Clock Frequency:** Up to 36 MHz (typical)  
- **Propagation Delay:** 30 ns (max)  
- **Power Consumption:** Low-power Schottky (LS) technology  

### **Descriptions:**  
The SN74LS164J is an 8-bit serial-in, parallel-out shift register that accepts serial data and outputs it in parallel. It features asynchronous Master Reset (MR) to clear all outputs. Data is shifted on the rising edge of the clock (CP).  

### **Features:**  
- **Serial Data Inputs (A & B):** Can be used independently or tied together.  
- **Parallel Outputs (Q0-Q7):** Provide 8-bit parallel output.  
- **Asynchronous Master Reset (MR):** Clears all outputs when low.  
- **Wide Operating Voltage:** Compatible with standard TTL levels.  
- **High-Speed Operation:** Suitable for serial-to-parallel data conversion.  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Serial-in shift registers

Alternative Part Number

  • DM74LS164N --: Same 8-bit serial-in/parallel-out shift register function in a DIP package, widely available and directly interchangeable in most designs.
  • MC74LS164N --: Pin-compatible LS-TTL 8-bit shift register from a different series prefix, suitable as a drop-in replacement with equivalent logic characteristics.
  • CD74HC164E --: CMOS 8-bit shift register with similar pinout and function; lower power consumption but check logic-level compatibility with LS-TTL inputs.
  • MC74HC164N --: Direct functional equivalent shift register from the successor of Motorola's logic line, offering similar electrical behavior and DIP compatibility.
  • 74LS164N --: Direct functional equivalent 8-bit serial-in/parallel-out shift register with LS TTL logic levels, common second source.
