Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic The TC74HC4020AFN is a 14-stage binary ripple counter manufactured by Toshiba. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (VCC):** 2V to 6V  
- **High-Level Input Voltage (VIH):** 3.15V (min) at VCC = 4.5V  
- **Low-Level Input Voltage (VIL):** 1.35V (max) at VCC = 4.5V  
- **High-Level Output Current (IOH):** -5.2mA (max) at VCC = 4.5V  
- **Low-Level Output Current (IOL):** 5.2mA (max) at VCC = 4.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DIP-16  

### **Descriptions:**  
- **Logic Type:** CMOS  
- **Function:** 14-stage binary ripple counter with an internal oscillator  
- **Clock Input:** Negative-edge triggered  
- **Reset Function:** Asynchronous master reset (active HIGH)  
- **Outputs:** Buffered for improved noise immunity  

### **Features:**  
- High-speed operation (typical propagation delay: 13ns at VCC = 5V)  
- Low power consumption (ICC = 4µA max at Ta = 25°C)  
- Wide operating voltage range (2V to 6V)  
- Compatible with TTL levels  
- High noise immunity  
- Schmitt trigger action on clock input for pulse shaping  

This information is based on Toshiba's datasheet for the TC74HC4020AFN.
