Description and Introduction

+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX231CWE is a dual RS-232 driver/receiver manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX231CWE  
- **Package:** 16-pin Wide SOIC (SOIC-16)  
- **Operating Voltage Range:** +4.5V to +5.5V  
- **Data Rate:** Up to 120kbps  
- **Number of Drivers/Receivers:** 2 Drivers, 2 Receivers  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Supply Current (No Load):** 5mA (Typical)  

### **Descriptions:**
The MAX231CWE is a dual RS-232 transceiver designed for serial communication applications. It includes two drivers and two receivers, making it suitable for full-duplex data transmission. The device operates from a single +5V power supply and includes an internal charge pump to generate the necessary RS-232 voltage levels (±7.5V). It is commonly used in industrial, telecom, and embedded systems requiring reliable serial communication.

### **Features:**
- Single +5V power supply operation  
- Onboard charge pump for RS-232 voltage generation  
- Meets EIA/TIA-232 and V.28/V.24 standards  
- Low power consumption  
- Enhanced ESD protection (±15kV)  
- Pin-compatible with industry-standard RS-232 transceivers  
- Available in a 16-pin wide SOIC package  

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

Application Scenarios & Design Considerations

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

Alternative Part Number

  • ICL232CPE --: Pin-compatible dual RS-232 driver/receiver in a 16-pin DIP, functionally equivalent to the MAX231 with similar supply requirements.
  • AD232JR --: Dual RS-232 transceiver offering comparable driver/receiver functionality and DIP packaging, suitable as a direct functional replacement.
  • LT1181ACN --: Dual RS-232 driver/receiver with on-chip charge pump, similar pinout and electrical characteristics for serial interface applications.
  • ST232CN --: Widely available dual RS-232 transceiver in DIP-16, drop-in functional replacement for MAX231 in most 5V applications.
  • HIN232CP --: Dual RS-232 driver/receiver with matching pinout and DIP-16 package, suitable as a direct functional substitute.
  • ADM232AAN --: Dual RS-232 line driver/receiver in a 16-pin DIP offering equivalent interface functionality and a well-established alternative to the MAX231.
