Description and Introduction

+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX234EWE is a product from Maxim Integrated (now part of Analog Devices). Below are the factual details about this part:

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

### **Part Number:**  
MAX234EWE  

### **Specifications:**  
- **Type:** RS-232 Transceiver  
- **Number of Drivers/Receivers:** 3 Drivers, 5 Receivers  
- **Data Rate:** Up to 120kbps  
- **Supply Voltage:** Single +5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin Wide SOIC (SO-16)  
- **Features:**  
  - Meets EIA/TIA-232 and V.28/V.24 specifications  
  - Onboard charge pump for ±10V output swing  
  - Low power consumption  
  - ESD protection on RS-232 pins (±15kV Human Body Model)  

### **Descriptions:**  
The MAX234EWE is a 3-driver, 5-receiver RS-232 transceiver designed for serial communication applications. It operates from a single +5V supply and includes an internal charge pump to generate the required RS-232 voltage levels (±10V). The device is compliant with EIA/TIA-232 and V.28/V.24 standards, making it suitable for interfacing with modems, computers, and other serial devices.  

### **Features:**  
- Single +5V power supply  
- Integrated charge pump for RS-232 voltage levels  
- 120kbps data rate  
- ESD protection (±15kV) on RS-232 I/O lines  
- Low power shutdown mode  
- Wide operating temperature range (-40°C to +85°C)  

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

Application Scenarios & Design Considerations
