Description and Introduction

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers The MAX490EEPA 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  
- **Low Power Consumption:**  
  - **Shutdown Current:** 1µA (max)  
  - **Quiescent Current (Driver Disabled):** 120µA (max)
