Description and Introduction

±15kV ESD-Protected, 1µA, 3.0V to 5.5V, 250kbps, RS-232 Transceivers with AutoShutdown The MAX3221EAE+ is a 3.0V to 5.5V powered, 1µA, 1Mbps, true RS-232 transceiver manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to 1Mbps  
- **Low Power Consumption:**  
  - 1µA shutdown current  
  - 300µA active supply current  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SSOP (AE)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Compliance:** Meets EIA/TIA-232 and V.28/V.24 standards  
- **Number of Drivers/Receivers:** 1 driver, 1 receiver  

### **Descriptions:**  
The MAX3221EAE+ is a single-driver, single-receiver RS-232 transceiver designed for low-power applications. It operates from a single 3.0V to 5.5V supply, making it suitable for battery-powered devices. The device includes an efficient charge-pump voltage doubler/inverter to generate RS-232 voltage levels (±5.5V) from a single supply.  

### **Features:**  
- **Auto-Shutdown:** Enters low-power mode (1µA) when no valid RS-232 signal is detected.  
- **Auto-Wakeup:** Automatically wakes up upon detecting an RS-232 signal.  
- **Enhanced ESD Protection:** ±15kV on transmitter outputs and receiver inputs.  
- **Small Footprint:** Available in a space-saving 16-pin SSOP package.  
- **Guaranteed Data Rate:** Ensures reliable communication up to 1Mbps.  
- **No External Components Required:** Internal charge pump eliminates the need for external capacitors in most applications.  

This device is commonly used in portable electronics, industrial systems, and embedded applications requiring RS-232 communication.
