Description and Introduction

QFN Packaged/ +/-15kV ESD Protected/ +2.7V to +5.5V/ 150Nanoamp/ 250kBps/ RS-232 Transmitters/Receivers The ISL4223EIR is a product from the manufacturer **INTERSIL** (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features of the ISL4223EIR:

### **Specifications:**
- **Manufacturer:** INTERSIL  
- **Type:** RS-422/RS-485 Interface IC  
- **Package:** 16-SOIC (150 mil)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage:** 4.5V to 5.5V  
- **Data Rate:** Up to 20Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  

### **Description:**
The ISL4223EIR is a high-speed, low-power RS-422/RS-485 transceiver designed for full-duplex communication. It integrates one differential driver and one differential receiver, making it suitable for industrial, telecom, and networking applications. The device supports high-speed data transmission while maintaining robust ESD protection.

### **Features:**
- **High-Speed Operation:** Supports data rates up to 20Mbps.  
- **Low Power Consumption:** Designed for energy-efficient applications.  
- **Wide Supply Range:** Operates from 4.5V to 5.5V.  
- **Enhanced ESD Protection:** ±15kV HBM protection on bus pins.  
- **Full-Duplex Communication:** Independent driver and receiver channels.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Short-Circuit Protection:** Robust against output faults.  
- **Compliant with Standards:** Meets RS-422 and RS-485 specifications.  

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

Alternative Part Number

  • MAX3232ECPE+ --: Pin-compatible RS-232 transceiver with similar dual-channel driver/receiver function and 3V/5V operation, widely available and well documented.
  • SP3232ECP-L --: Direct functional equivalent RS-232 transceiver with ESD protection, same DIP package and supply range, often used as a drop-in replacement.
  • ST3232ECTR --: Low-power RS-232 transceiver with comparable driver/receiver count and supply voltage, suitable alternative when the original is unavailable.
  • ST3232ECDR --: Low-power RS-232 transceiver offering similar driver/receiver configuration and supply range, usable as an alternative with minor layout checks.
