Description and Introduction

8-STAGE STATIC SHIFT REGISTER (ASYNCHRONOUS PARALLEL INPUT OR SYNCHRONOUS PARALLEL INPUT OR SYNCHRONOUS SERIAL INPUT/SERIAL OUTPUT The TC4021BF is a CMOS 8-stage static shift register manufactured by Toshiba (TC.PHI).  

### **Specifications:**  
- **Logic Type:** 8-stage static shift register  
- **Technology:** CMOS  
- **Supply Voltage (VDD):** 3V to 18V  
- **High Noise Immunity:** CMOS level  
- **Low Power Consumption**  
- **Wide Operating Voltage Range**  
- **Pin-Compatible with 4000 Series CMOS Logic**  

### **Descriptions & Features:**  
- **8-Bit Parallel or Serial Input/Serial Output Shift Register**  
- **Serial Data Input (DS)** for shifting data in  
- **Parallel Data Inputs (P0-P7)** for loading data  
- **Clock Input (CP)** for synchronous shifting  
- **Clock Inhibit Input (INH)** to disable clocking  
- **Master Reset (MR)** for clearing the register  
- **Outputs (Q6, Q7, Q8)** for serial output and cascading
