Description and Introduction

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers The MAX483ECSA 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:** MAX483ECSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Quiescent Current:** 120µA (typical)  
- **Shutdown Current:** 0.1µA (typical)  

### **Descriptions:**  
- The MAX483ECSA is a low-power RS-485/RS-422 compliant transceiver designed for half-duplex communication.  
- It features reduced slew-rate drivers to minimize EMI and reflections, making it suitable for electrically noisy environments.  
- Includes fail-safe circuitry to ensure a high receiver output state when inputs are open or shorted.  

### **Features:**  
- **Low Power Consumption:** Operates with a quiescent current of 120µA.  
- **Slew-Rate Limited:** Reduces EMI and allows error-free data transmission.  
- **Half-Duplex Operation:** Supports bidirectional communication on a single twisted-pair line.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Receiver Input Hysteresis:** Improves noise immunity.  
- **Compatible with RS-485 & RS-422 Standards:** Ensures reliable communication in industrial applications.  

This information is based solely on the manufacturer's datasheet.
