Description and Introduction

+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX222CWN is a product from Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features based on available knowledge:

### **Manufacturer:**  
- **MAXIM (Maxim Integrated)** – Now part of Analog Devices.  

### **Part Number:**  
- **MAX222CWN**  

### **Description:**  
The MAX222CWN is a **RS-232 transceiver** designed for serial communication applications. It is part of Maxim's line of interface ICs, providing reliable data transmission over RS-232 standards.  

### **Key Features:**  
1. **RS-232 Compliance:**  
   - Meets EIA/TIA-232-F and ITU V.28 standards.  
2. **Number of Drivers/Receivers:**  
   - **2 Drivers** and **2 Receivers** (full-duplex operation).  
3. **Supply Voltage:**  
   - Single **+5V** power supply operation.  
4. **Data Rate:**  
   - Supports up to **120kbps** data transmission rate.  
5. **ESD Protection:**  
   - Provides **±15kV** ESD protection (Human Body Model) on transmitter outputs and receiver inputs.  
6. **Low Power Consumption:**  
   - Features a low-power shutdown mode for power-sensitive applications.  
7. **Package:**  
   - **20-pin Wide SOIC (CWN package).**  
8. **Operating Temperature Range:**  
   - **Commercial (0°C to +70°C).**  

### **Applications:**  
- Industrial control systems.  
- Point-of-sale (POS) terminals.  
- Modems and serial communication interfaces.  
- Embedded systems requiring RS-232 connectivity.  

This information is based on the manufacturer's datasheet and technical documentation. For exact details, refer to the official datasheet from Analog Devices (formerly Maxim Integrated).

Application Scenarios & Design Considerations

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

Alternative Part Number

  • ADM202EARNZ --: Pin-compatible dual RS-232 transceiver with integrated charge pump, functionally equivalent to the MAX222 and widely available.
  • ST202CDR --: Low-cost dual RS-232 driver/receiver in SOIC package, drop-in functional replacement for MAX222 in most designs.
  • ICL202CPE --: Classic dual RS-232 transceiver with on-chip charge pump, same function and pinout family as the MAX222.
  • ADM202EANZ --: Pin-compatible dual RS-232 transceiver in a 16-pin DIP, functionally equivalent to the MAX222 with integrated charge pump capacitors.
  • ST202ECN --: Dual RS-232 driver/receiver in 16-pin DIP with similar supply and data-rate specs, a common drop-in substitute for MAX222.
  • ADM202EAN --: Pin-compatible dual RS-232 transceiver with comparable driver/receiver count and supply voltage, widely available and often used as a direct substitute.
