Description and Introduction

±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers The **MAX487ECSA+T** is a low-power transceiver manufactured by **Maxim Integrated (now part of Analog Devices)**. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **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:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Half/Full Duplex:** Half-Duplex  
- **Current Consumption (Quiescent):** 120µA (typical)  

### **Descriptions:**  
The **MAX487ECSA+T** 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, making it suitable for applications requiring robust data transmission over long distances.  

### **Features:**  
- Low power consumption (120µA quiescent current)  
- Slew-rate-limited driver for reduced EMI  
- Half-duplex communication  
- Up to 2.5Mbps data rate  
- Allows up to 32 transceivers on the bus  
- Thermal shutdown protection  
- Short-circuit current limiting  
- ESD protection (±15kV)  

This transceiver is commonly used in industrial control systems, building automation, and other applications requiring reliable differential communication.
