Description and Introduction

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX483MJA is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** +4.75V to +5.25V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Interface Type:** RS-485, RS-422  
- **Package:** 8-Pin CERDIP (MJA)  

### **Descriptions:**  
- The MAX483MJA 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.  
- Suitable for half-duplex communication in industrial, military, and harsh environments.  

### **Features:**  
- **Low Power Consumption:** Typically 120µA in shutdown mode.  
- **Slew-Rate Limited Driver:** Minimizes EMI and reduces reflections.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **High Input Impedance:** Allows up to 32 transceivers on the bus.  
- **Receiver Fail-Safe:** Ensures logic-high output when inputs are open or shorted.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official documentation.
