Description and Introduction

15KV ESD PROTECTED, 3 TO 5.5 V LOW POWER UP TO 250KBPS, RS232 DRIVERS AND RECEIVERS The **ST3232ECTR** is a dual driver/receiver IC designed by STMicroelectronics, primarily used for RS-232 communication. Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Supply Voltage (VCC):** 3.0V to 5.5V  
- **Data Rate:** Up to 400 kbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 2 Drivers, 2 Receivers  
- **ESD Protection:** ±15 kV (Human Body Model)  
- **Package:** TSSOP-16  

### **Descriptions:**  
- The ST3232ECTR is a low-power, 3V to 5.5V RS-232 transceiver compliant with EIA/TIA-232 and V.28/V.24 standards.  
- It includes an onboard charge pump for generating RS-232 voltage levels (±5.5V) from a single 3V to 5.5V supply.  
- Suitable for battery-powered and portable applications due to its low power consumption.  

### **Features:**  
- **Low Power Consumption:** Ideal for power-sensitive applications.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge.  
- **Auto-Powerdown:** Reduces power consumption when not in use.  
- **Wide Supply Voltage Range:** Supports 3V to 5.5V operation.  
- **Compact Package:** TSSOP-16 for space-constrained designs.  

This IC is commonly used in industrial control, networking, and embedded systems requiring reliable RS-232 communication.
