Description and Introduction

±15kV ESD Protected, 3V to 5.5V, 1μA, 250kbps, RS-232 Transmitters/Receivers The **ICL3223EIA** is a dual transmitter/receiver RS-232 interface IC manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to **250kbps**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Number of Drivers/Receivers:** **2 Drivers, 2 Receivers**  
- **ESD Protection:** **±15kV (Human Body Model)**  
- **Package Type:** **16-lead SOIC (Small Outline IC)**  
- **Compliance:** Meets **EIA/TIA-232-F** standards  

### **Descriptions:**
- The ICL3223EIA is a **low-power, 3V to 5.5V RS-232 transceiver** designed for serial communication.  
- It integrates **two drivers and two receivers**, making it suitable for full-duplex communication.  
- The device includes **on-board charge pumps**, eliminating the need for external ±12V power supplies.  
- It is optimized for **portable and battery-powered applications** due to its low power consumption.  

### **Features:**
- **Low Power Consumption:**  
  - **1µA (Typical) shutdown current**  
  - **300µA (Typical) active supply current**  
- **Auto-Powerdown Feature:** Automatically enters low-power mode when no signal is detected.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to **±15kV** (HBM).  
- **Wide Supply Voltage Range:** Supports **3V to 5.5V** operation, making it compatible with 3.3V and 5V systems.  
- **Small Footprint:** Available in a **16-pin SOIC package**, suitable for space-constrained designs.  

This information is sourced from the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

±15kV ESD Protected, 3V to 5.5V, 1μA, 250kbps, RS-232 Transmitters/Receivers

Alternative Part Number

  • MAX3232ECAE+ --: Pin-compatible RS-232 transceiver with similar 3V/5V operation and ESD protection, widely used as a direct substitute for the ICL3223 series.
  • SP3232ECA-L --: Equivalent RS-232 transceiver in the same SSOP package with comparable data rate and supply voltage range, suitable drop-in replacement.
  • ST3232ECTR --: Low-power RS-232 transceiver offering similar functionality and package compatibility, a cost-effective alternative for the ICL3223EIA.
