Description and Introduction

±15kV ESD Protected, 3V to 5.5V, 1μA, 250kbps, RS-232 Transmitters/Receivers The **ICL3221ECVZ** is a **3.3V-powered RS-232 transceiver** manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage:** 3.0V to 5.5V (single supply)  
- **Data Rate:** Up to **250kbps**  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **16-pin TSSOP**  
- **Number of Drivers/Receivers:** **1 Driver, 1 Receiver**  
- **Interface Type:** **RS-232**  
- **Low Power Consumption:** Typically **1µA** in shutdown mode  

### **Descriptions:**
- The **ICL3221ECVZ** is a **single-channel RS-232 transceiver** designed for **low-power, portable applications**.  
- It complies with **EIA/TIA-232-F** standards and is suitable for **battery-powered systems** due to its low power consumption.  
- The device includes an **internal charge pump** for generating RS-232 voltage levels from a single **3.3V supply**.  

### **Features:**
- **3.3V Operation** (compatible with 5V logic inputs)  
- **Auto Shutdown/Enable** (reduces power when not in use)  
- **Onboard DC-DC Converters** (eliminates the need for external voltage converters)  
- **Small Footprint** (16-pin TSSOP package for space-constrained designs)  
- **Enhanced ESD Protection** (±15kV HBM on transmitter outputs and receiver inputs)  
- **Meets or Exceeds EIA/TIA-232-F Standards**  

This device is commonly used in **portable electronics, industrial systems, and embedded applications** requiring **RS-232 communication**.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • MAX3221ECAE+ --: Pin-compatible RS-232 transceiver with similar 3V/5V operation and auto-shutdown, widely available and functionally equivalent.
  • SP3221ECY-L --: Direct functional equivalent RS-232 transceiver with comparable data rate and low-power shutdown, suitable drop-in replacement.
  • ST3221ECDR --: Similar single-channel RS-232 transceiver with charge pump and auto-powerdown, good alternative when Maxim/MaxLinear parts are unavailable.
