One microamp supply-current, +3V to +5.5V, 250kbps, RS-232 transmitter/receiver The ICL3223CA is a dual-channel RS-232 transceiver manufactured by **INTERSIL**. Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to **250 kbps**  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** **0°C to +70°C**  
- **Package:** **16-pin SOIC**  
- **Compliance:** Meets **EIA/TIA-232-F** standards  

### **Descriptions:**
- The **ICL3223CA** is a **3V-powered** dual RS-232 transceiver designed for **low-power** applications.  
- It integrates **two drivers and two receivers**, supporting full-duplex communication.  
- The device includes **on-board charge pumps**, eliminating the need for external ±12V power supplies.  

### **Features:**
- **Low Power Consumption:** Operates with a **single 3V to 5.5V supply**.  
- **Auto-Powerdown:** Reduces power consumption when inactive.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to **±15kV**.  
- **Small Footprint:** Available in a **16-pin SOIC package** for space-constrained designs.  
- **Compatible with 5V Logic:** Works seamlessly with both **3V and 5V logic levels**.
