Description and Introduction

Fail-Safe / High-Speed 10Mbps / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX3089CSD is a high-speed RS-485/RS-422 transceiver manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX3089CSD  
- **Package:** 14-SOIC (150 mil)  
- **Supply Voltage:** 4.75V to 5.25V  
- **Data Rate:** Up to 25Mbps  
- **Operating Temperature Range:** 0°C to +70°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Common-Mode Voltage Range (Receiver):** ±25V  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Half/Full Duplex:** Half Duplex  
- **Fail-Safe Receiver:** Yes (Open, Short, Terminated)  

### **Descriptions:**  
The MAX3089CSD is a high-speed, low-power RS-485/RS-422 transceiver designed for robust communication in noisy environments. It features enhanced slew-rate limiting for reduced EMI and reflections, making it suitable for high-speed data transmission up to 25Mbps. The device includes fail-safe circuitry to ensure a logic-high receiver output when inputs are open or shorted.  

### **Features:**  
- **High-Speed Operation:** Supports data rates up to 25Mbps.  
- **Low Power Consumption:** Typically 120µA supply current in shutdown mode.  
- **Enhanced Slew-Rate Limiting:** Reduces EMI and signal reflections.  
- **ESD Protection:** ±15kV protection on bus pins.  
- **Fail-Safe Receiver:** Ensures valid output under open, shorted, or terminated conditions.  
- **Wide Common-Mode Range:** ±25V for robust noise immunity.  
- **Half-Duplex Operation:** Suitable for bidirectional communication.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  

This information is strictly based on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

Fail-Safe / High-Speed 10Mbps / Slew-Rate-Limited RS-485/RS-422 Transceivers

Alternative Part Number

  • SN65HVD3082EDR --: Pin-compatible RS-485 transceiver with similar half-duplex functionality and widely available as a drop-in replacement.
  • ADM485ARZ --: Industry-standard RS-485 transceiver offering comparable data rate and electrical characteristics for similar applications.
  • ISL8485EIBZ --: Robust RS-485/RS-422 transceiver with ESD protection, suitable functional substitute when exact MAXIM part is unavailable.
  • SP490CS-L --: Pin-compatible RS-485 transceiver in the same SOIC-14 footprint, offering equivalent half-duplex operation and a different naming series for easy distinction.
  • SN75176BDR --: Widely available RS-485 differential bus transceiver with similar electrical characteristics, commonly used as a drop-in substitute in industrial networks.
