Description and Introduction

1 microamp, +3V to +5.5V, 250kbps, RS-232 transceivers with enhanced automatic powerdown The ICL3226CA is a dual-channel RS-232 transceiver manufactured by **INTERSIL** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage:** +3.0V to +5.5V  
- **Data Rate:** Up to **400 kbps**  
- **Operating Temperature Range:** **0°C to +70°C**  
- **Number of Drivers/Receivers:** **2 Drivers, 2 Receivers**  
- **ESD Protection:** **±15kV (Human Body Model)**  
- **Package Type:** **16-pin SOIC (Small Outline Integrated Circuit)**  
- **Compliance:** Meets **EIA/TIA-232-F** and **ITU-T V.28** standards  

### **Descriptions:**  
- The ICL3226CA is a **low-power, dual-channel RS-232 transceiver** designed for **serial data communication**.  
- It integrates **charge-pump circuitry** to generate RS-232 voltage levels from a single **3V to 5.5V supply**, eliminating the need for external ±12V power supplies.  
- Suitable for **portable devices, industrial systems, and embedded applications** requiring RS-232 communication.  

### **Features:**  
- **Auto-Shutdown/Low-Power Mode:** Reduces power consumption when not in use.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge (ESD) up to **±15kV**.  
- **Small Footprint:** Available in a **16-pin SOIC package**, making it suitable for space-constrained designs.  
- **Wide Supply Voltage Range:** Operates from **3.0V to 5.5V**, compatible with 3.3V and 5V systems.  
- **Compatible with 5V Logic Inputs:** Ensures seamless interfacing with microcontrollers and UARTs.  

This information is strictly based on the manufacturer's datasheet and technical documentation. No additional recommendations or interpretations are included.

Application Scenarios & Design Considerations

1 microamp, +3V to +5.5V, 250kbps, RS-232 transceivers with enhanced automatic powerdown

Alternative Part Number

  • MAX3226CAE+ --: Pin-compatible RS-232 transceiver with auto-shutdown in the same 20-pin SSOP package; widely available and functionally equivalent to the ICL3226CA.
  • SP3226ECY-L --: Direct functional replacement RS-232 transceiver with auto-online feature, 3V/5V operation, and matching pinout in SSOP-20.
  • ST3222ECDR --: Low-power RS-232 transceiver with similar 3V operation and shutdown capability; suitable drop-in alternative when exact package matching is verified.
