Description and Introduction

8-BIT PARALLEL-LOAD SHIFT REGISTERS The SN74HC165 from Texas Instruments (TI) is an 8-bit parallel-load shift register with the following specifications, descriptions, and features:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** SN74HC165  

### **Description:**  
- The SN74HC165 is an 8-bit parallel-in/serial-out shift register.  
- It is designed to convert parallel data inputs into a serial output stream.  
- The device features a serial data input (DS), a clock input (CP), a shift/load input (SH/LD), and complementary outputs (Q7 and Q7').  

### **Key Features:**  
- **Supply Voltage Range:** 2V to 6V  
- **High-Current 3-State Outputs:** Can drive up to 15 LSTTL loads  
- **Low Power Consumption:** 80 µA (max) ICC  
- **Operating Temperature Range:** -40°C to 85°C  
- **Fast Switching Speed:** tpd = 13 ns (typical) at 5V  
- **Schmitt-Trigger Inputs:** Allows for slow input transition and better noise immunity  
- **Parallel-to-Serial Data Conversion:** 8-bit parallel input with serial output  
- **Asynchronous Parallel Load:** Loads data independently of the clock  
- **Package Options:** PDIP, SOIC, TSSOP  

### **Applications:**  
- Data storage and transfer  
- Serial-to-parallel conversion  
- Remote control systems  
- Industrial automation  

This device is part of TI's HC logic family, which offers high-speed CMOS performance while maintaining low power consumption.

Application Scenarios & Design Considerations

8-BIT PARALLEL-LOAD SHIFT REGISTERS

Alternative Part Number

  • MC74HC165ADG --: Same 8-bit parallel-in/serial-out shift register function in HC logic family, widely available and pin-compatible in SOIC package.
  • CD74HC165E --: Equivalent HC-series 8-bit parallel-load shift register from the same logic family, direct functional replacement with similar electrical characteristics.
  • 74HC165D,653 --: Standard 74HC165 shift register in SO16 package, functionally identical and a common second-source alternative.
  • MC74HC165AN --: Industry-standard 74HC165 shift register from a different series prefix, same logic function and pinout, widely available second source.
  • 74HC165D --: Equivalent 8-bit parallel-load shift register in SOIC package, different manufacturer and naming, suitable drop-in replacement for SMD designs.
