Description and Introduction

Software-Selectable Multiprotocol Transceiver The LTC1343 is a low-power RS232 transceiver manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** 3V to 5.5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Data Rate:** Up to 250kbps  
- **Low Supply Current:** 300µA (typical) in shutdown mode  
- **ESD Protection:** ±15kV (Human Body Model) on RS232 I/O pins  
- **Number of Drivers/Receivers:** 3 Drivers, 5 Receivers  
- **Package Options:** 20-Pin SSOP, 28-Pin SSOP  

### **Description:**  
The LTC1343 is a 3-driver/5-receiver RS232 transceiver designed for low-power applications. It operates from a single 3V to 5.5V supply and includes an onboard charge pump to generate RS232 voltage levels (±5V to ±10V). The device features a shutdown mode to minimize power consumption when not in use.  

### **Features:**  
- Single 3V to 5.5V supply operation  
- Onboard charge pump for RS232 voltage levels  
- Low power consumption (300µA in shutdown)  
- ESD-protected RS232 I/O pins (±15kV)  
- Three RS232 drivers and five receivers  
- Flow-through pinout simplifies PCB layout  
- Operates up to 250kbps data rate  
- Available in SSOP packages
