One microamp supply-current, +3V to +5.5V, 250kbps, RS-232 transmitter/receiver The ICL3232IV is a dual-channel RS-232 transceiver manufactured by **INTERSIL** (now part of Renesas Electronics).  

### **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-Lead SOIC (Small Outline IC)  
- **Compliance:** Meets EIA/TIA-232-F standards  

### **Descriptions:**  
- The ICL3232IV is a low-power, dual-channel RS-232 transceiver.  
- It includes two drivers and two receivers, enabling full-duplex communication.  
- Designed for battery-powered and portable applications due to its low power consumption.  

### **Features:**  
- **Auto-Powerdown:** Reduces power consumption when not in use.  
- **On-Chip Charge Pump:** Eliminates the need for external ±12V supplies.  
- **Low Power Consumption:** Typically 1mA in active mode.  
- **Receiver Hysteresis:** Improves noise immunity.  
- **Wide Supply Voltage Range:** Supports 3V to 5.5V operation.  

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