Description and Introduction

3.0V to 5.5V RS-232 Transceivers with Auto On-Line? Plus The SP3224EEY-L is a 3.0V to 5.5V RS-232 transceiver manufactured by Exar Corporation. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 3.0V to 5.5V  
- **Data Rate:** Up to 1Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 3 drivers, 5 receivers  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  
- **ESD Protection:** ±15kV (Human Body Model) on transmitter outputs and receiver inputs  
- **Low Power Consumption:**  
  - Active Mode: 1mA (typical)  
  - Shutdown Mode: 1µA (typical)  

### **Descriptions:**
- The SP3224EEY-L is a low-power RS-232 transceiver designed for battery-powered and portable applications.  
- It complies with EIA/TIA-232-F standards and supports full-duplex communication.  
- The device includes an integrated charge pump for generating RS-232 voltage levels from a single 3V to 5.5V supply.  

### **Features:**
- **Auto Shutdown/Enable:** Automatically enters low-power mode when no valid signal is detected.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge on RS-232 lines.  
- **Small Footprint:** 28-pin SSOP package for space-constrained designs.  
- **Wide Supply Voltage Range:** Supports operation from 3.0V to 5.5V, making it suitable for mixed-voltage systems.  
- **On-Board Charge Pump:** Eliminates the need for external voltage converters.  

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

Application Scenarios & Design Considerations

3.0V to 5.5V RS-232 Transceivers with Auto On-Line? Plus

Alternative Part Number

  • MAX3224EEAP+ --: Pin-compatible RS-232 transceiver with similar 250kbps data rate and 3V/5V operation, widely available and well documented.
  • ICL3224ECAZ --: Direct functional equivalent RS-232 transceiver in the same family class, supports auto-power-down and matches the SP3224EEY-L feature set.
  • ST3224ECDR --: Low-power RS-232 transceiver with comparable driver/receiver count and supply range, suitable drop-in replacement for most SP3224EEY-L applications.
