Description and Introduction

+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX225EWI is a high-speed, low-power RS-232 transceiver manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
Maxim Integrated (now part of Analog Devices)  

### **Description:**  
The MAX225EWI is a 5V-powered RS-232 transceiver designed for high-speed data communication. It integrates charge-pump circuitry to generate RS-232 voltage levels (±10V) from a single 5V supply, eliminating the need for external power supplies.  

### **Key Features:**  
- **Single 5V Power Supply:** Generates RS-232 compliant ±10V outputs.  
- **Low Power Consumption:** Typically consumes 5mA of supply current.  
- **High Data Rate:** Supports up to **120kbps** data transmission.  
- **Integrated Charge Pump:** No external capacitors required.  
- **ESD Protection:** ±15kV Human Body Model (HBM) on I/O lines.  
- **Package:** 28-pin Wide SOIC (SOIC-W) package.  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Compliance:** Meets EIA/TIA-232 and V.28/V.24 standards.  
- **Number of Drivers/Receivers:** 5 drivers and 3 receivers.  

### **Applications:**  
- Industrial control systems  
- Point-of-sale terminals  
- Battery-powered devices  
- Modems and serial communication interfaces  

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

Application Scenarios & Design Considerations

Alternative Part Number

  • ADM241LJR --: Pin-compatible RS-232 transceiver with similar driver/receiver count and supply voltage, widely used as a MAX225 substitute.
  • ST202ECDR --: Dual RS-232 driver/receiver in SOIC package with comparable electrical characteristics and lower cost.
  • ICL3221ECAZ --: RS-232 transceiver offering equivalent functionality and ESD protection, suitable drop-in replacement in most designs.
  • ST232CWR --: Low-cost 5V RS-232 transceiver offering comparable functionality and pinout, suitable for direct substitution in most MAX225 applications.
  • ICL232CPE --: Classic dual RS-232 driver/receiver with similar electrical characteristics and DIP/SOIC options, a well-established alternative for MAX225 designs.
