ICL3223IA

One microamp supply-current, +3V to +5.5V, 250kbps, RS-232 transmitter/receiver The **ICL3223IA** is a **3.3V-powered RS-232 transceiver** manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage:** **3.3V ±10%**  
- **Data Rate:** **250kbps** (guaranteed)  
- **ESD Protection:** **±15kV** (Human Body Model)  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **16-pin SOIC (IA suffix)**  
- **Number of Drivers/Receivers:** **2 Drivers, 2 Receivers**  
- **Compliance:** Meets **EIA/TIA-232-F** and **ITU-T V.28** standards  

### **Descriptions:**
- The **ICL3223IA** is a **low-power, high-performance RS-232 transceiver** designed for **3.3V systems**.  
- It features **on-board charge-pump voltage converters**, eliminating the need for external ±12V power supplies.  
- Suitable for **battery-powered, portable, and embedded applications** due to its low power consumption.  

### **Features:**
- **Auto-Powerdown Plus™** feature for reduced power consumption when idle.  
- **Enhanced ESD protection** (±15kV HBM) on transmitter outputs and receiver inputs.  
- **Small footprint** (SOIC-16 package).  
- **Wide input voltage range** (accepts 5V logic inputs when powered by 3.3V).  
- **Low supply current** (typically **1mA** in active mode).  

This device is commonly used in **industrial, telecom, and computing applications** where **RS-232 communication** is required in **3.3V systems**.  

(Note: Always refer to the **official datasheet** for complete and updated specifications.)
