Description and Introduction

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX488MJA is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX488MJA  
- **Package:** 8-Pin CERDIP (J-Lead)  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Supply Voltage Range:** +4.75V to +5.25V  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Interface Type:** RS-485/RS-422  

### **Descriptions:**  
- The MAX488MJA is a low-power, half-duplex RS-485/RS-422 transceiver designed for balanced communication.  
- It is suitable for military and industrial applications due to its wide temperature range and rugged CERDIP package.  
- The device features reduced slew-rate drivers to minimize EMI and reflections in unterminated cables.  

### **Features:**  
- **Low Power Consumption:**  
  - 120µA supply current (unloaded)  
  - 1µA shutdown current  
- **Half-Duplex Communication:** Supports bidirectional data transmission.  
- **Enhanced ESD Protection:** ±15kV on driver outputs and receiver inputs.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Slew-Rate Limited Drivers:** Reduces EMI and allows error-free data transmission.  
- **Wide Common-Mode Voltage Range:** ±7V for robust noise immunity.  
- **Compliance:** Meets RS-485 and RS-422 standards.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
