Description and Introduction

DECADE COUNTER/DIVIDER The M74HC4017B1R is a high-speed CMOS decade counter/divider with 10 decoded outputs, manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Logic Family:** HC (High-speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Maximum Clock Frequency:** 50 MHz (at 6V)  
- **Low Power Consumption:** 4 µA (typical)  
- **Output Current:** ±5.2 mA (at 6V)  
- **Package:** SO-16 (Small Outline)  

### **Descriptions:**  
- The M74HC4017B1R is a 5-stage Johnson counter with 10 decoded outputs (Q0-Q9).  
- It features a carry output (CO) for cascading multiple counters.  
- The counter advances on the rising edge of the clock signal when the clock enable (CE) input is low.  
- A reset (MR) input allows the counter to be cleared to Q0.  

### **Features:**  
- **10 Decoded Outputs:** Each output goes high sequentially.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Wide Operating Voltage:** Compatible with 2V to 6V systems.  
- **High Noise Immunity:** CMOS technology ensures reliable operation.  
- **Cascadable:** Multiple counters can be connected using the carry output.  
- **Schmitt Trigger Clock Input:** Improves noise rejection.  

This information is based on the manufacturer's datasheet and technical documentation.
