Description and Introduction

Timer The SE555CN is a precision timer IC manufactured by **PHILIPS** (now part of NXP Semiconductors). Below are the key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Supply Voltage Range:** 4.5V to 16V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Output Current (Sink or Source):** Up to 200mA  
- **Timing Accuracy:** ±2% over temperature range  
- **Power Consumption:** Low (typically 10mA at 15V)  
- **Trigger Voltage:** Typically 1/3 of VCC  
- **Threshold Voltage:** Typically 2/3 of VCC  
- **Reset Voltage:** ≤ 0.7V  

### **Descriptions:**  
- The SE555CN is a monolithic timing circuit designed for stable operation in various applications.  
- It can function as a **monostable (one-shot) or astable (oscillator) multivibrator**.  
- It is compatible with the industry-standard **NE555/SE555** series.  

### **Features:**  
- Adjustable duty cycle  
- High output current capability  
- TTL-compatible output  
- Temperature stability  
- Available in **8-pin DIP (Dual In-line Package)**  

This IC is widely used in timing, pulse generation, and delay applications.  

*(Note: PHILIPS' semiconductor division is now part of NXP Semiconductors, but the SE555CN retains the original branding.)*
