Description and Introduction

8-Bit Shift Registers The SN74LS166ML1 is a 8-bit parallel-in/serial-out shift register manufactured by Texas Instruments (MOT refers to Motorola, but TI is the correct manufacturer).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** Parallel-in, Serial-out Shift Register  
- **Number of Bits:** 8  
- **Operating Voltage:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC-16  
- **Clock Frequency:** Up to 25 MHz  
- **Input Type:** TTL-Compatible  
- **Output Type:** 3-State  

### **Descriptions and Features:**  
- **Parallel-to-Serial Conversion:** Loads data in parallel and shifts it out serially.  
- **Synchronous Operation:** Controlled by a clock input.  
- **Serial Data Input:** Allows cascading multiple devices.  
- **Asynchronous Clear:** Resets the register independently of the clock.  
- **3-State Output:** Enables bus-oriented applications.  
- **Low Power Consumption:** Typical of LS series logic.  
- **Applications:** Data storage, serial data transfer, and digital signal processing.  

This device is commonly used in digital systems for serial data transmission and signal processing tasks.

Application Scenarios & Design Considerations

8-Bit Shift Registers

Alternative Part Number

  • DM74LS166N --: Same 8-bit parallel-in/serial-out shift register function in the 74LS logic family, widely available and pin-compatible in DIP packages.
  • 74LS166AP --: Direct functional equivalent 8-bit shift register from the 74LS series, well-documented and commonly stocked alternative.
  • MC74LS166N --: Motorola-lineage 74LS166 shift register with identical logic function, suitable as a drop-in replacement in most designs.
  • CD74HC166E --: 8-bit parallel-in/serial-out shift register with the same function as the SN74LS166, using a different logic family and prefix for easy distinction.
  • MC74HC165ADG --: 8-bit parallel-load shift register in the 74HC family, functionally similar and widely available from a different manufacturer.
  • SN74HC165N --: 8-bit parallel-in/serial-out shift register in the HC family, offering lower power consumption and a different series designation.
  • 74LS166N --: Direct functional equivalent 8-bit shift register from the standard 74LS series, commonly stocked and electrically compatible.
