- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (MAX3072EESA)  
- **Half-Duplex Operation**  
- **Low-Power Shutdown Mode (1µA typical)**  
- **Receiver Input Impedance:** ≥12kΩ  
- **Driver Output Short-Circuit Current Limit**  
- **Compliant with RS-485 and RS-422 Standards**  

### **Features:**  
- **Enhanced ESD Protection:** Protects against electrostatic discharges up to ±15kV.  
- **High-Speed Operation:** Supports data rates up to 20Mbps.  
- **Low Power Consumption:** Features a low-power shutdown mode.  
- **Fault Protection:** Includes thermal shutdown and short-circuit protection.  
- **Wide Common-Mode Range:** Allows ±7V on bus pins for noise immunity.  
- **Hot-Swap Input Structure:** Prevents false transitions during power-up.  

### **Applications:**
