Description and Introduction

Fail-Safe / High-Speed 10Mbps / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX3080ESD is a high-speed, low-power RS-485/RS-422 transceiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** +4.5V to +5.5V  
- **Data Rate:** Up to 10Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Package:** 14-Pin SOIC (Small Outline Integrated Circuit)  
- **Receiver Input Impedance:** ≥12kΩ  
- **Driver Output Voltage (VOD):** ±1.5V (min) into 54Ω load  
- **Quiescent Current:** 300µA (max) in shutdown mode  

### **Descriptions:**  
The MAX3080ESD is a half-duplex RS-485/RS-422 transceiver designed for high-speed communication in industrial and automotive applications. It features enhanced electrostatic discharge (ESD) protection, making it suitable for harsh environments. The device operates from a single +5V supply and includes a low-power shutdown mode to conserve energy when not in use.  

### **Features:**  
- **High-Speed Operation:** Supports data rates up to 10Mbps.  
- **Low Power Consumption:** 300µA (max) shutdown current.  
- **Enhanced ESD Protection:** ±15kV on bus pins (Human Body Model).  
- **Half-Duplex Communication:** Single driver and receiver for bidirectional data transfer.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Wide Common-Mode Range:** -7V to +12V for robust noise immunity.  
- **Failsafe Receiver:** Ensures a logic-high output when inputs are open or shorted.  

This information is based on the manufacturer's datasheet for the MAX3080ESD.
