Description and Introduction

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX490EPA is a low-power, slew-rate-limited RS-485/RS-422 transceiver manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage (VCC):** +4.75V to +5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 2.5Mbps  
- **Slew Rate Limited:** Reduces EMI and reflections in unterminated cables  
- **Low Power Consumption:**  
  - **Shutdown Current:** 1µA (max)  
  - **Quiescent Current:** 120µA (max)  
- **Driver Output Short-Circuit Current Limit:** 250mA  
- **Receiver Input Impedance:** ≥12kΩ  
- **Receiver Input Sensitivity:** ±200mV  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions and Features:**  
- Designed for half-duplex communication in RS-485/RS-422 networks.  
- Includes slew-rate-limited drivers to minimize EMI and signal reflections.  
- Features a low-power shutdown mode (consumes only 1µA).  
- Provides fail-safe receiver operation (outputs high when inputs are open or shorted).  
- Robust ESD protection (±15kV) on driver outputs and receiver inputs.  
- Supports up to 32 unit loads on a single bus.  
- Suitable for industrial control, automotive, and telecom applications.
