Description and Introduction

One microamp supply-current, +3V to +5.5V, 250kbps, RS-232 transmitter/receiver The ICL3222IA is a dual RS-232 transceiver manufactured by INTERSIL. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** INTERSIL  
- **Type:** Dual RS-232 Transceiver  
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to 250kbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SOIC (Small Outline Integrated Circuit)  
- **Compliance:** Meets EIA/TIA-232-F and ITU-T V.28 standards  
- **ESD Protection:** ±15kV (Human Body Model)  

### **Descriptions:**
- The ICL3222IA is a low-voltage, dual-channel RS-232 transceiver designed for serial communication applications.  
- It integrates two drivers and two receivers in a single package, making it suitable for full-duplex communication.  
- The device operates from a single power supply (3.0V to 5.5V) and includes an internal charge pump for RS-232 voltage level generation.  

### **Features:**
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Auto-Powerdown:** Automatically enters low-power shutdown mode when not in use.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to ±15kV.  
- **Wide Supply Voltage Range:** Supports 3.0V to 5.5V operation.  
- **Small Footprint:** Available in a 16-pin SOIC package for space-constrained designs.  
- **Compatible with 3V/5V Logic:** Interfaces seamlessly with both 3V and 5V microcontrollers.  

This information is strictly based on the available knowledge base for the ICL3222IA by INTERSIL.

Alternative Part Number

  • MAX3222CWP --: Pin-compatible RS-232 transceiver with dual charge pump, direct functional equivalent to the ICL3222 in a 20-pin SOIC/wide package.
  • SP3222ECA --: 3V/5V RS-232 transceiver with matching driver/receiver count and charge-pump architecture, commonly used as a drop-in replacement.
  • ADM3222ARW --: Low-power RS-232 transceiver with equivalent 2-driver/2-receiver configuration and similar supply range, suitable as an alternative.
  • MAX3222CPN --: Pin-compatible RS-232 transceiver with same 3V/5V operation and dual charge pump; widely available drop-in replacement for the ICL3222IA.
  • ST3222CDR --: Equivalent 3V/5V RS-232 transceiver with matching pinout and charge-pump architecture, suitable as a second-source alternative.
