Description and Introduction

Dual Timer The KA556I is a dual timer IC manufactured by Fairchild Semiconductor. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage (VCC):** 4.5V to 16V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Current (Sink or Source):** Up to 200mA  
- **Power Dissipation:** 600mW  
- **Timing Capacitance Range:** 100pF to 100μF  
- **Timing Resistance Range:** 1kΩ to 100kΩ  

### **Description:**  
The KA556I consists of two independent 555 timer circuits in a single package. Each timer operates similarly to the standard 555 timer IC, capable of functioning in astable (oscillator) or monostable (one-shot) modes. The device is designed for precision timing, pulse generation, and sequential timing applications.  

### **Features:**  
- **Dual 555 Timer:** Two independent timers in one package.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **High Output Current:** Can drive TTL loads directly.  
- **Adjustable Duty Cycle:** Configurable for astable operation.  
- **Wide Operating Voltage Range:** Compatible with 5V, 12V, and 15V systems.  
- **Temperature Stability:** Maintains performance across industrial temperature ranges.  

The KA556I is commonly used in applications such as oscillators, pulse generators, time-delay circuits, and sequential timing systems.  

(Note: Always refer to the official Fairchild datasheet for precise technical details.)
