Description and Introduction

Complete, Isolated RS-485/RS-422 Data Interface The MAX1480BEPI is a high-speed, low-power RS-485/RS-422 transceiver manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage:** 4.75V to 5.25V  
- **Data Rate:** Up to 2.5Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin PDIP (Plastic Dual In-Line Package)  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Low Power Consumption:**  
  - **Shutdown Mode:** 1µA (typical)  
  - **Active Mode (No Load):** 120µA (typical)  

### **Descriptions:**  
- The MAX1480BEPI is designed for full-duplex RS-485/RS-422 communication.  
- It features slew-rate-limited drivers to reduce EMI and minimize reflections in unterminated cables.  
- Includes fail-safe circuitry to ensure a logic-high receiver output when inputs are open or shorted.  

### **Features:**  
- **Half/Full-Duplex Operation**  
- **Slew-Rate Limited for Reduced EMI**  
- **Thermal Shutdown Protection**  
- **Short-Circuit Current Limiting**  
- **Low-Power Shutdown Mode**  
- **Compatible with RS-485 and RS-422 Standards**

Application Scenarios & Design Considerations

Complete, Isolated RS-485/RS-422 Data Interface

Alternative Part Number

  • ADM2483BRWZ --: Isolated RS-485/RS-422 transceiver in a similar DIP-28 footprint, functionally equivalent to the MAX1480B with integrated isolation, widely available and well documented.
  • IL485E --: Isolated RS-485 transceiver offering comparable isolation and data-rate performance, suitable as a drop-in functional replacement for the MAX1480B in industrial communication designs.
  • ISO485 --: Isolated RS-485 transceiver family member with similar isolation rating and signaling characteristics, providing a viable alternative when the MAX1480B is unavailable.
