Description and Introduction

3 TO 5.5V, LOW POWER, UP TO 400KBPS RS-232 DRIVERS AND RECEIVERS The ST3232BDR is a dual driver/receiver device manufactured by STMicroelectronics. It is designed for RS-232 and V.28 communication interfaces, operating with a single 3.0V to 5.5V power supply.  

### **Key Specifications:**  
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to 250 kbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **ESD Protection:** ±15 kV (Human Body Model)  
- **Package:** SO-16  

### **Features:**  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Auto-Powerdown:** Reduces power consumption when not in use.  
- **Compliant with EIA/TIA-232-F Standards:** Ensures compatibility with RS-232 interfaces.  
- **Two Drivers and Two Receivers:** Supports full-duplex communication.  
- **3-State Outputs:** Allows bus sharing in multidrop applications.  

### **Applications:**  
- Battery-powered systems  
- PDAs, laptops, and notebooks  
- Handheld equipment  
- Industrial controls
