Description and Introduction

±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers The MAX487EPA+ 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  
- **Part Number:** MAX487EPA+  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Interface Type:** RS-485, RS-422  
- **Receiver Input Impedance:** ≥12kΩ  
- **ESD Protection:** ±15kV (Human Body Model)  

### **Descriptions:**  
The MAX487EPA+ 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 noise-sensitive applications. The device operates with a single 5V supply and includes fail-safe circuitry to ensure a high receiver output when inputs are open or shorted.  

### **Features:**  
- **Low Power Consumption:**  
  - 120µA (Quiescent Current)  
  - 0.1µA (Shutdown Mode)  
- **Slew-Rate-Limited Driver for Reduced EMI**  
- **Half-Duplex Communication**  
- **Allows up to 128 Transceivers on the Bus**  
- **Thermal Shutdown Protection**  
- **Receiver Hysteresis for Noise Immunity**  
- **Compliant with TIA/EIA-485-A Standards**  

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