Description and Introduction

Fail-Safe / High-Speed 10Mbps / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX3082CSA is a high-speed, low-power RS-485/RS-422 transceiver manufactured by Maxim Integrated. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** +4.5V to +5.5V  
- **Data Rate:** Up to 10Mbps  
- **Operating Temperature Range:** 0°C to +70°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Quiescent Current:** 300µA (typical)  
- **Receiver Input Impedance:** ≥12kΩ  
- **Driver Output Voltage (VOD):** ±1.5V (min)  
- **Common-Mode Input Voltage Range:** -7V to +12V  
- **Package:** 8-pin SOIC  

### **Descriptions:**
The MAX3082CSA is a half-duplex transceiver designed for RS-485/RS-422 communication. It features high-speed data transmission, low power consumption, and robust ESD protection. The device is suitable for industrial, automotive, and networking applications requiring reliable long-distance communication.

### **Features:**
- **High-Speed Operation:** Supports data rates up to 10Mbps.  
- **Low Power Consumption:** 300µA typical quiescent current.  
- **ESD Protection:** ±15kV protection on bus pins.  
- **Half-Duplex Communication:** Single driver and receiver for bidirectional data transfer.  
- **Wide Common-Mode Range:** Allows operation in noisy environments.  
- **Thermal Shutdown:** Prevents damage from excessive power dissipation.  
- **Short-Circuit Protection:** Driver outputs are protected against short circuits.  
- **Fail-Safe Receiver:** Ensures logic-high output when inputs are open or shorted.  

These details are based on the manufacturer's datasheet for the MAX3082CSA.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • SN75176BDR --: Industry-standard RS-485/RS-422 transceiver with the same half-duplex function and 8-pin SOIC footprint; widely available and pin-compatible in most designs.
  • SP485ECN-L --: Pin-compatible RS-485 transceiver in SOIC-8 with similar data rate and supply range, offering a direct drop-in replacement from a different series.
  • ST485ECDR --: Low-power RS-485/RS-422 transceiver in SOIC-8 with comparable electrical characteristics and ESD protection, suitable as a functional substitute.
  • ISL8485EIBZ --: RS-485/RS-422 transceiver with comparable performance and pinout, suitable drop-in replacement for MAX3082CSA.
