Description and Introduction

/-15kV ESD Protected, 3V to 5.5V, 1Microamp, 250kbps, RS-232 Transceivers with Enhanced Automatic Powerdown The **ICL3244ECA-T** is a quad RS-232 transceiver manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Intersil (Renesas Electronics)  
- **Type:** Quad RS-232 Transceiver  
- **Operating Voltage:** 3V to 5.5V  
- **Data Rate:** Up to 250 kbps  
- **Number of Drivers/Receivers:** 4 Drivers / 4 Receivers  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead TSSOP  

### **Descriptions:**  
- The ICL3244ECA-T is a low-power, quad RS-232 transceiver designed for serial communication applications.  
- It supports both 3V and 5V logic levels, making it suitable for mixed-voltage systems.  
- Features enhanced ESD protection, making it robust in harsh environments.  
- Compliant with EIA/TIA-232-F and ITU-T V.28 standards.  

### **Features:**  
- **Low Power Consumption:** Operates with a single 3V to 5.5V supply.  
- **Auto-Powerdown:** Reduces power consumption when not in use.  
- **High-Speed Data Transmission:** Supports up to 250 kbps.  
- **Integrated Charge Pump:** Eliminates the need for external voltage converters.  
- **Enhanced ESD Protection:** ±15kV (HBM) on transmitter outputs and receiver inputs.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  

This device is commonly used in **industrial control, networking, and embedded systems** requiring reliable RS-232 communication.
