Description and Introduction

±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers The MAX489EESD+ is a low-power transceiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX489EESD+  
- **Type:** RS-485/RS-422 Transceiver  
- **Supply Voltage:** +4.75V to +5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Package:** 14-SOIC  
- **Mounting Type:** Surface Mount  
- **ESD Protection:** ±15kV (Human Body Model)  

### **Descriptions:**  
The MAX489EESD+ is a low-power, slew-rate-limited transceiver designed for RS-485 and RS-422 communication. It features reduced EMI and reflections due to its slew-rate-limited driver. The device operates from a single +5V supply and includes fail-safe circuitry, ensuring a logic-high receiver output when inputs are open or shorted.  

### **Features:**  
- **Low Power Consumption:**  
  - 120μA supply current (shutdown mode)  
  - 900μA quiescent current (active mode)  
- **Slew-Rate-Limited Driver:** Reduces EMI and reflections.  
- **Full-Duplex Communication:** Supports simultaneous transmit and receive.  
- **Extended Common-Mode Range:** ±12V for robust noise immunity.  
- **Thermal Shutdown Protection:** Prevents damage during fault conditions.  
- **Receiver Open-Circuit Fail-Safe:** Ensures a logic-high output when inputs are unconnected.
