Description and Introduction

8-Bit Shift Register (P-IN, S-OUT) The TC74HC166AFN is a parallel-load 8-bit shift register manufactured by Toshiba. 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  
- **Package Type:** 16-pin DIP (Plastic)  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **High-Level Output Current:** -5.2mA  
- **Low-Level Output Current:** 5.2mA  
- **Propagation Delay Time:** 20ns (typical at 5V)  
- **Maximum Clock Frequency:** 50MHz (at 5V)  

### **Descriptions:**  
- The TC74HC166AFN is an 8-bit parallel-in/serial-out shift register with synchronous operation.  
- It features a serial data input (DS) and eight parallel data inputs (D0-D7).  
- Data is loaded in parallel via the parallel load (PL) input and shifted out serially via the clock (CP) input.  
- It includes an asynchronous master reset (MR) to clear the register.  

### **Features:**  
- **Parallel-to-Serial Conversion:** Loads 8-bit data in parallel and outputs serially.  
- **Synchronous Operation:** Shifts data on the rising edge of the clock.  
- **Asynchronous Reset:** Clears all flip-flops when the MR input is low.  
- **Wide Operating Voltage:** Supports 2V to 6V, making it compatible with various logic levels.  
- **High-Speed Operation:** Fast propagation delay and high clock frequency.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  

This information is based solely on the manufacturer's datasheet for the TC74HC166AFN.

Application Scenarios & Design Considerations

8-Bit Shift Register (P-IN, S-OUT)

Alternative Part Number

  • SN74HC166AN --: Pin-compatible 8-bit parallel-load shift register in the same 74HC logic family, widely available and functionally equivalent.
  • MC74HC166AN --: Direct functional equivalent 8-bit shift register with parallel load, same HC CMOS technology and DIP package.
  • CD74HC166E --: Equivalent 8-bit parallel-in/serial-out shift register in HC logic, suitable drop-in replacement for the original function.
  • MC74HC166ANG --: Equivalent HC-series 8-bit PISO shift register with matching logic and DIP-16 pinout, good second source.
  • MC74HC166ADG --: Same 74HC166 function with compatible electrical characteristics and pinout, offered in SOIC package as a drop-in replacement.
