Description and Introduction

Fail-Safe / High-Speed 10Mbps / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX3082ESA is a low-power, RS-485/RS-422 transceiver manufactured by Maxim Integrated. Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX3082ESA  
- **Package:** 8-SOIC (150mil)  
- **Supply Voltage:** +4.5V to +5.5V  
- **Data Rate:** Up to 250kbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Quiescent Current:** 120µA (Typical)  
- **Receiver Input Impedance:** ≥12kΩ  
- **Driver Output Current:** ±60mA (Short-Circuit Protected)  

### **Descriptions:**  
The MAX3082ESA is a low-power, half-duplex RS-485/RS-422 transceiver designed for balanced communication. It features reduced slew-rate drivers to minimize EMI and reflections in unterminated networks. The device operates from a single +5V supply and includes thermal shutdown protection to prevent damage from excessive power dissipation.  

### **Features:**  
- **Low Power Consumption:** 120µA quiescent current (typical)  
- **Half-Duplex Operation**  
- **Reduced Slew Rate for Low EMI**  
- **Thermal Shutdown Protection**  
- **Receiver Failsafe for Open/Shorted Inputs**  
- **ESD Protection on RS-485 I/O Pins (±15kV HBM)**  
- **Compatible with RS-485 and RS-422 Standards**  

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