Description and Introduction

Dual Timer The LM556CN is a dual timer IC manufactured by National Semiconductor (国半). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Dual 555 Timer IC  
- **Supply Voltage Range:** 4.5V to 16V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Output Current (Sink/Source):** 200mA (max)  
- **Trigger Voltage:** Typically 1/3 of VCC  
- **Threshold Voltage:** Typically 2/3 of VCC  
- **Reset Voltage:** ≤ 0.4V (active low)  
- **Power Consumption:** Low (varies with supply voltage)  
- **Package:** 14-Pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The LM556CN consists of two independent 555 timer circuits in a single package.  
- Each timer operates similarly to a standard 555 timer, providing precision timing and pulse generation.  
- It can be used in monostable (one-shot) or astable (oscillator) modes.  

### **Features:**  
- **Dual Timer:** Two fully independent 555 timers in one IC.  
- **Wide Operating Voltage:** Works from 4.5V to 16V.  
- **High Output Drive:** Capable of sourcing or sinking up to 200mA.  
- **Adjustable Duty Cycle:** Configurable for precise timing control.  
- **Compatible with TTL and CMOS Logic:** Can interface with digital circuits.  
- **Stable and Monostable Operation:** Supports both timing modes.  
- **Low Power Consumption:** Efficient for battery-operated applications.  

This information is strictly based on the manufacturer's specifications for the LM556CN.
