Description and Introduction

One microamp supply-current, +3V to +5.5V, 250kbps, RS-232 transmitter/receiver The ICL3222IB is a dual-channel RS-232 transceiver manufactured by **Intersil** (now part of Renesas Electronics). Below are the key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to 250kbps  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SOIC (Small Outline Integrated Circuit)  
- **Compliance:** Meets EIA/TIA-232-F standards  

### **Description:**  
The ICL3222IB is a low-power, dual-channel RS-232 transceiver designed for serial communication applications. It integrates charge-pump circuitry to generate RS-232 voltage levels from a single 3V to 5.5V supply, eliminating the need for external power supplies.  

### **Features:**  
- **Dual Transmitter/Receiver Channels**  
- **Auto-Powerdown Feature** for reduced power consumption  
- **Low Supply Current:** 1mA (typical)  
- **On-Chip Capacitors** for charge-pump voltage conversion  
- **3V to 5.5V Operation**  
- **Compatible with 5V Logic**  
- **Enhanced ESD Protection** on RS-232 I/O pins  

This device is commonly used in battery-powered systems, PDAs, laptops, and embedded applications requiring RS-232 communication.
