Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic 8-Bit Shift Register (P-IN, S-OUT) The TC74AC166P is a parallel-in/serial-out shift register manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Logic Family:** AC  
- **Logic Type:** Shift Register  
- **Number of Bits:** 8  
- **Input Type:** Parallel-In/Serial-Out  
- **Output Type:** Serial  
- **Supply Voltage Range:** 2V to 5.5V  
- **High-Level Output Current:** -24mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 7.5ns (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** DIP-16  

### **Descriptions:**
- The TC74AC166P is an 8-bit parallel-in/serial-out shift register with synchronous operation.  
- It features a serial input (DS) and parallel load capability (PL).  
- Data is shifted on the rising edge of the clock (CP).  
- It includes an asynchronous master reset (MR) for clearing the register.  

### **Features:**
- **High-Speed Operation:** Suitable for AC series performance.  
- **Wide Operating Voltage:** Supports 2V to 5.5V.  
- **Parallel Load Function:** Enables direct data input.  
- **Low Power Consumption:** Optimized for efficiency.  
- **Schmitt Trigger Inputs:** Improves noise immunity.  
- **Asynchronous Reset:** Allows immediate clearing of the register.  

This information is based solely on Toshiba's datasheet for the TC74AC166P.
