Description and Introduction

Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers The **MAX483CUA+T** is a low-power RS-485/RS-422 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  
- **Package:** 8-pin µMAX (UMAX)  
- **Operating Voltage:** +4.75V to +5.25V  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** 0°C to +70°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Supply Current (Quiescent):** 120µA (Max)  
- **Receiver Input Impedance:** ≥12kΩ  
- **Driver Output Short-Circuit Current Limit:** ±250mA  

### **Descriptions:**
- The **MAX483CUA+T** is designed for half-duplex communication in RS-485/RS-422 networks.  
- It features reduced slew-rate drivers to minimize EMI and reflections in unterminated cables.  
- Suitable for low-power applications due to its low quiescent current.  

### **Features:**
- **Low Power Consumption:** 120µA quiescent current.  
- **Slew-Rate Limited:** Reduces EMI and signal reflections.  
- **Extended Common-Mode Range:** ±7V for robust noise immunity.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Receiver Fail-Safe:** Ensures a logic-high output when inputs are open or shorted.  
- **Compatible with 3.3V and 5V Systems.**  

This transceiver is commonly used in industrial control, building automation, and point-to-point data transmission systems.
