Description and Introduction

3.3V, 460 Kbps RS-232 Transceivers The SP3222EHCY is a 3.0V to 5.5V RS-232 transceiver manufactured by SIPEX (now part of Exar Corporation).  

### **Specifications:**  
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to 235 kbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SSOP (Shrink Small Outline Package)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Low Power Consumption:** Auto Shutdown/Enable feature  
- **Compliance:** Meets EIA/TIA-232-F standards  
- **Number of Drivers/Receivers:** 2 drivers, 2 receivers  

### **Descriptions:**  
The SP3222EHCY is a low-power RS-232 transceiver designed for battery-powered and portable applications. It includes an efficient charge pump to generate RS-232 voltage levels from a single 3V to 5.5V supply.  

### **Features:**  
- **Auto Shutdown:** Automatically enters low-power mode when no signal is detected.  
- **Auto Enable:** Wakes up upon detecting an RS-232 signal.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to ±15kV.  
- **Small Footprint:** 16-pin SSOP package for space-constrained designs.  
- **Wide Supply Range:** Operates from 3.0V to 5.5V, making it suitable for mixed-voltage systems.  

This transceiver is commonly used in industrial, consumer, and communication applications requiring reliable RS-232 communication.
