Description and Introduction

5V Low Power RS232 3-Driver/5-Receiver Transceiver with 2 Receivers Active in SHUTDOWN The LTC1349IG is a manufacturer part from Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features based on available knowledge:

### **Manufacturer:**  
Linear Technology (now part of Analog Devices)  

### **Part Number:**  
LTC1349IG  

### **Package:**  
28-Lead SSOP (Shrink Small Outline Package)  

### **Description:**  
The LTC1349IG is a **Triple RS232 Transceiver** designed for applications requiring multiple RS232 ports in a compact form factor. It integrates three full-duplex RS232 transceivers with enhanced ESD protection.  

### **Key Features:**  
1. **Triple RS232 Transceiver** – Supports three independent full-duplex RS232 channels.  
2. **Low Power Consumption** – Operates with a single **5V supply**.  
3. **Enhanced ESD Protection** – ±15kV (Human Body Model) on all transmitter outputs and receiver inputs.  
4. **High Data Rate** – Supports up to **250kbps** data transmission.  
5. **On-Chip Charge Pump** – Eliminates the need for external ±12V supplies by generating RS232 voltage levels internally.  
6. **Shutdown Mode** – Reduces power consumption when not in use.  
7. **Wide Operating Temperature Range** – Typically **-40°C to 85°C**.  
8. **Compact SSOP Package** – Suitable for space-constrained applications.  

### **Applications:**  
- Multi-port RS232 communication systems  
- Industrial control interfaces  
- Networking equipment  
- Point-of-sale terminals  
- Embedded systems requiring multiple serial ports  

This information is based on the manufacturer’s datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official datasheet from Analog Devices.
