Description and Introduction

3.0V to 5.5V, Low-Power, Up to 1Mbps, True RS-232 Transceivers Using Four 0.1µF External Capacitors The MAX3222 is a dual driver/receiver device manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** +3.0V to +5.5V  
- **Data Rate:** Up to 250kbps  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Low Power Consumption:**  
  - 1µA (Typical) in shutdown mode  
  - 300µA (Typical) in active mode  
- **Number of Drivers/Receivers:** 2 Drivers, 2 Receivers  
- **Interface Standards:** RS-232  

### **Description:**
The MAX3222 is a dual RS-232 transceiver designed for serial communication in low-power applications. It integrates two drivers and two receivers, supporting bidirectional data transmission. The device includes an efficient charge-pump voltage doubler/inverter to generate RS-232 voltage levels from a single 3V to 5.5V supply.  

### **Features:**
- **Auto-Shutdown/Enable:** Automatically enters low-power mode when the RS-232 cable is disconnected.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to ±15kV.  
- **Small Package Options:** Available in space-saving SOIC, TSSOP, and µMAX packages.  
- **Compatible with 3V/5V Logic:** Works with both 3.3V and 5V systems.  
- **On-Board Charge Pump:** Eliminates the need for external voltage converters.

- **Low Power Consumption:** 1µA (Shutdown Mode)  
- **Package Options:** SOIC, TSSOP, µMAX  

### **Descriptions:**
- The MAX3222 is a dual RS-232 transceiver designed for low-power applications.  
- It complies with EIA/TIA-232 and V.28/V.24 communication standards.  
- The device includes a charge-pump voltage converter to generate RS-232 voltage levels from a single power supply.  
- It features auto-shutdown and wake-up functions to minimize power consumption.  

### **Features:**
- **Auto-Shutdown:** Automatically enters low-power mode when no valid signal is detected.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to ±15kV.  
- **Low Supply Current:** Typically 300µA in active mode.  
- **Small Footprint:** Available in space-saving packages like µMAX.  
- **Onboard Charge Pump:** Eliminates the need for external ±12V power supplies.  
- **Receiver Hysteresis:** Improves noise immunity in electrically noisy environments.
