Description and Introduction

3 TO 5.5V, 250KBPS, RS-232 TRANSCEIVER WITH STAND-BY The ST3237B is a low-power RS-232 transceiver manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **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)  
- **Number of Drivers/Receivers:** 2 drivers, 2 receivers  
- **Package Options:** SO-16, TSSOP-16  

### **Descriptions:**
- The ST3237B is a 3.0V to 5.5V-powered RS-232 transceiver designed for low-power applications.  
- It complies with EIA/TIA-232-F standards and is suitable for battery-powered devices.  
- The device includes an onboard charge pump, eliminating the need for external ±12V supplies.  

### **Features:**
- **Low Power Consumption:** Optimized for battery-operated systems.  
- **Auto-Powerdown:** Reduces power consumption when not in use.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to ±15 kV.  
- **Wide Supply Voltage Range:** Supports 3.0V to 5.5V operation.  
- **Compact Packages:** Available in SO-16 and TSSOP-16 for space-constrained designs.  

This information is based solely on the manufacturer's datasheet.

Application Scenarios & Design Considerations

3 TO 5.5V, 250KBPS, RS-232 TRANSCEIVER WITH STAND-BY

Alternative Part Number

  • MAX3237E --: Pin-compatible RS-232 transceiver with similar 3-driver/5-receiver configuration and 1Mbps data rate, widely used as a direct substitute for ST3237B.
  • SP3237E --: Equivalent RS-232 transceiver offering the same driver/receiver count and supply voltage range, commonly cross-referenced for ST3237B in serial interface designs.
  • ICL3237E --: Functionally equivalent 3.0V to 5.5V RS-232 transceiver with matching pinout and ESD protection, suitable as a drop-in alternative to ST3237B.
