Description and Introduction

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers The MAX483EESA is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX483EESA  
- **Package:** 8-SOIC (150mil)  
- **Operating Voltage:** +4.75V to +5.25V  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** -40°C to +85°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Quiescent Current:** 120µA (typical)  
- **Shutdown Current:** 0.1µA (typical)  

### **Descriptions:**  
- The MAX483EESA is a low-power RS-485/RS-422 compliant transceiver designed for half-duplex communication.  
- It features reduced slew-rate drivers to minimize EMI and reduce reflections in unterminated cables.  
- Suitable for industrial control, telecom, and battery-powered applications due to its low power consumption.  

### **Features:**  
- **Low Power Consumption:** Operates at 120µA (typical) quiescent current.  
- **Slew-Rate Limited Drivers:** Reduces EMI and allows error-free data transmission.  
- **ESD Protection:** ±15kV protection on driver outputs and receiver inputs.  
- **Thermal Shutdown:** Prevents damage during fault conditions.  
- **Receiver Fail-Safe:** Ensures logic-high output when inputs are open or shorted.  
- **1/8 Unit Load:** Allows up to 256 transceivers on the bus.  
- **Shutdown Mode:** Reduces power consumption to 0.1µA when disabled.  

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

Application Scenarios & Design Considerations

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers

Alternative Part Number

  • SN75176BDR --: Industry-standard RS-485/RS-422 transceiver in SOIC-8, pin-compatible with MAX483 and widely available as a direct functional replacement.
  • SP483ECN-L --: Low-power half-duplex RS-485 transceiver with the same SOIC-8 footprint and similar slew-rate-limited driver characteristics.
  • ST485ECDR --: RS-485/RS-422 transceiver in SOIC-8 with comparable data rate and supply range, suitable as a cost-effective drop-in alternative.
  • ADM485ARZ --: Pin-compatible RS-485 transceiver in SOIC-8 with similar data rate and drive capability, a common drop-in replacement for MAX483.
  • SP485ECN-L --: RS-485 transceiver in SOIC-8 with equivalent half-duplex operation and ESD protection, suitable as a functional substitute.
