Description and Introduction

+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX220CWE is a product from Maxim Integrated (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX220CWE  
- **Package:** 16-Wide SOIC (SO)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Supply Voltage:** ±5V to ±12V  
- **Number of Drivers/Receivers:** 2 Drivers, 2 Receivers  
- **Data Rate:** Up to 120kbps  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Interface Type:** RS-232  

### **Descriptions:**
The MAX220CWE is a dual RS-232 line driver/receiver designed for serial communication applications. It operates from a single +5V power supply with onboard charge pumps to generate the necessary RS-232 voltage levels (±10V). It is compliant with EIA/TIA-232-F standards and is suitable for battery-powered and low-power systems.

### **Features:**
- Single +5V Power Supply Operation  
- Onboard Charge Pump for RS-232 Voltage Levels  
- Low Power Consumption  
- Meets EIA/TIA-232-F and V.28/V.24 Standards  
- Two Drivers and Two Receivers  
- ±15kV ESD Protection on I/O Pins  
- Operates Up to 120kbps Data Rate  
- Available in 16-Pin SOIC Package  

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

Application Scenarios & Design Considerations

+5V-Powered, Multichannel RS-232 Drivers/Receivers

Alternative Part Number

  • ADM202EARNZ --: Pin-compatible RS-232 transceiver in a 16-pin SOIC package with similar dual-driver/receiver functionality and widely available as a drop-in replacement.
  • ST202CDR --: Equivalent 5V RS-232 transceiver with two drivers and two receivers, matching the MAX220 function and commonly used as a lower-cost alternative.
  • SP202ECP-L --: Direct functional equivalent RS-232 transceiver from a different series, offering the same driver/receiver count and 5V operation for serial interface designs.
  • ST202ECDR --: Low-cost dual RS-232 driver/receiver with similar electrical characteristics and 16-pin SOIC footprint, suitable for direct substitution in most designs.
  • ICL202CPE --: Classic MAX220-equivalent RS-232 transceiver offering the same driver/receiver count and supply requirements, usable as a functional alternative with minor layout checks.
