- **Package Type:** DIP (Dual In-line Package)  
- **Operating Temperature Range:** -55°C to +100°C  

### **Descriptions:**  
The **LCA127** is an optocoupler designed to provide electrical isolation between input and output circuits. It consists of an infrared LED optically coupled to a phototransistor, ensuring signal transmission without direct electrical connection.  

### **Features:**  
- High isolation voltage for safety in high-voltage applications  
- Fast response time for switching applications  
- Compact DIP package for easy PCB mounting  
- Wide operating temperature range for industrial use  
- Reliable signal transmission in noisy environments  

For exact values (e.g., CTR, VCEO), refer to the specific datasheet as variations may exist.
