Description and Introduction

1 Microamp, +3V to +5.5V, 250kbps, RS-232 Transceivers with Enhanced Automatic Powerdown The **ICL3244IA** is a quad RS-232 transceiver manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Intersil  
- **Type:** Quad RS-232 Transceiver  
- **Operating Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to 250kbps  
- **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 SSOP  

### **Descriptions:**
- The ICL3244IA is a low-power, quad RS-232 transceiver designed for serial communication applications.  
- It complies with EIA/TIA-232-F standards and is suitable for battery-powered systems due to its low power consumption.  
- The device integrates charge-pump circuitry to generate RS-232 voltage levels from a single 3V to 5.5V supply.  

### **Features:**
- **Low Power Consumption:** Auto-shutdown and auto-wakeup features reduce power usage.  
- **Enhanced ESD Protection:** ±15kV HBM protection on transmitter outputs and receiver inputs.  
- **Wide Supply Voltage Range:** Operates from 3.0V to 5.5V.  
- **High Data Rate:** Supports up to 250kbps transmission speed.  
- **On-Chip Charge Pump:** Eliminates the need for external voltage converters.  
- **Flow-Through Pinout:** Simplifies PCB layout.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations
