Description and Introduction

15KV ESD PROTECTED, 3 TO 5.5 V LOW POWER UP TO 250KBPS, RS232 DRIVERS AND RECEIVERS The ST3232EB is a dual driver/receiver device manufactured by STMicroelectronics. It is designed for RS-232 and V.28/V.24 communication interfaces, particularly in harsh environments.  

### **Specifications:**  
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to 400 kbps  
- **ESD Protection:** ±15 kV (Human Body Model)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Low Power Consumption:** 1 µA in standby mode  
- **Package Options:** TSSOP (20-pin), SOIC (20-pin)  

### **Descriptions:**  
- The ST3232EB is a 3V-powered RS-232 transceiver with two drivers and two receivers.  
- It complies with EIA/TIA-232-F standards.  
- Suitable for battery-powered applications due to low power consumption.  

### **Features:**  
- **Enhanced ESD Protection:** Protects against electrostatic discharges.  
- **Wide Supply Voltage Range:** Operates from 3V to 5.5V.  
- **Auto-Powerdown:** Automatically enters low-power mode when not in use.  
- **Driver Output Swing:** Ensures RS-232-compliant voltage levels.  
- **Receiver Input Hysteresis:** Improves noise immunity.  

This device is commonly used in industrial, telecom, and portable applications requiring reliable serial communication.
