Description and Introduction

15KV ESD PROTECTED, 3 TO 5.5V 400KBPS, RS-232 TRANSCEIVER WITH AUTO-POWERDOWN The ST3243ECTR is a quad differential line driver and receiver designed for RS-232 and V.28 communication interfaces. Here are the key specifications, descriptions, and features from the manufacturer (STMicroelectronics):

### **Specifications:**
- **Supply Voltage (VCC):** 3V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 1Mbps  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Package:** TSSOP-20  
- **Number of Drivers/Receivers:** 4 Drivers / 5 Receivers  
- **Output Voltage Swing (RS-232):** ±5V (min)  
- **Supply Current (Active):** 1mA (typical)  
- **Shutdown Current:** <1µA  

### **Descriptions:**
- The ST3243ECTR is a low-power, high-performance transceiver compliant with EIA/TIA-232-F and ITU-T V.28 standards.  
- It integrates capacitive charge-pump circuitry to generate RS-232 voltage levels from a single 3V to 5.5V supply.  
- The device includes four drivers, five receivers, and a dual charge-pump converter.  
- It is designed for battery-powered and portable applications requiring reliable serial communication.  

### **Features:**
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **Auto-Powerdown:** Enters low-power mode when not in use.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge.  
- **Wide Supply Voltage Range:** Supports 3V to 5.5V operation.  
- **Compatible with 3V and 5V Logic:** Ensures flexibility in interfacing.  
- **High Data Rate:** Supports up to 1Mbps transmission speed.
