Description and Introduction

15KV ESD PROTECTED 5V RS-232 TRANSCEIVER The ST232EC is a dual driver/receiver device from STMicroelectronics, designed for RS-232 communication.  

### **Specifications:**  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 120 kbps  
- **ESD Protection:** ±15 kV (Human Body Model)  
- **Number of Drivers/Receivers:** 2 drivers, 2 receivers  
- **Package Options:** SO-16, TSSOP-16  

### **Descriptions:**  
- The ST232EC is a 5V-powered RS-232 transceiver, compliant with EIA/TIA-232-F standards.  
- It includes an onboard charge pump to generate ±9V RS-232 voltage levels from a single 5V supply.  
- Suitable for battery-powered and portable applications due to low power consumption.  

### **Features:**  
- **Onboard Charge Pump:** Eliminates the need for external ±12V supply.  
- **Low Power Consumption:** Designed for power-sensitive applications.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge.  
- **Wide Supply Voltage Range:** Operates reliably from 4.5V to 5.5V.  
- **Compatible with 3V Logic Inputs:** Ensures flexibility in interfacing with different microcontrollers.  

This device is commonly used in industrial control, data communication, and embedded systems requiring RS-232 connectivity.

Application Scenarios & Design Considerations

15KV ESD PROTECTED 5V RS-232 TRANSCEIVER

Alternative Part Number

  • MAX232ECPE --: Pin-compatible RS-232 transceiver with ESD protection, widely used as a drop-in replacement for the ST232EC in 5V systems.
  • SP232ECP --: Equivalent RS-232 line driver/receiver with similar ESD ratings and pinout, suitable for direct substitution.
  • ICL232CPE --: Classic dual RS-232 transmitter/receiver with compatible functionality and DIP package, usable as an alternative with minor external component checks.
