Description and Introduction

3.0V to 5.5V RS-232 Transceivers with Auto On-Line? Plus The SP3226EEA-L is a RS-232 transceiver IC manufactured by Exar Corporation. Below are the specifications, descriptions, and features based on factual information:

### **Manufacturer:**  
Exar Corporation (now part of MaxLinear)  

### **Specifications:**  
- **Interface Type:** RS-232  
- **Number of Drivers/Receivers:** 3 Drivers / 5 Receivers  
- **Data Rate:** Up to 235 kbps  
- **Operating Voltage:** 3.0V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Low Power Consumption:**  
  - Active Mode: 1 mA (typical)  
  - Shutdown Mode: 1 μA (typical)  

### **Description:**  
The SP3226EEA-L is a 3.3V-powered RS-232 transceiver designed for low-power applications. It complies with EIA/TIA-232-F standards and is suitable for battery-operated devices due to its low power consumption. The device includes an integrated charge pump for generating RS-232 voltage levels from a single 3.3V supply.  

### **Features:**  
- **Auto Shutdown/Enable:** Automatically enters low-power mode when not in use.  
- **Enhanced ESD Protection:** ±15kV on transmitter outputs and receiver inputs.  
- **Wide Power Supply Range:** Operates from 3.0V to 5.5V.  
- **Small Footprint:** 28-pin SSOP package for space-constrained applications.  
- **Compatibility:** Works with 5V logic levels despite being a 3.3V device.  
- **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

  • MAX3226EEAE+ --: Pin-compatible RS-232 transceiver with auto-shutdown, same 3.0V-5.5V supply range and SSOP-16 package, widely available and functionally equivalent.
  • ICL3226EIAZ --: RS-232 transceiver with 1uA auto-shutdown, matches the SP3226E feature set and SSOP-16 footprint, good second-source option.
  • ST3222ECDR --: Low-power RS-232 transceiver in SOIC-16 with similar supply and data-rate specs; acceptable drop-in for many SP3226E designs with minor layout adjustment.
