Description and Introduction

【15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers The MAX481ECPA is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX481ECPA  
- **Package:** 8-Pin PDIP (Plastic Dual In-line Package)  
- **Supply Voltage Range:** +4.75V to +5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Interface Type:** RS-422/RS-485  
- **Low Power Consumption:**  
  - **Shutdown Current:** ≤1µA  
  - **Quiescent Current (No Load):** 120µA (Typical)  
- **ESD Protection:** ±15kV (Human Body Model)  

### **Descriptions:**  
The MAX481ECPA is a low-power, slew-rate-limited transceiver designed for RS-485 and RS-422 communication. It features a single driver and receiver, making it suitable for half-duplex applications. The device includes built-in protection against electrostatic discharge (ESD) and is optimized for low-power operation, making it ideal for battery-powered or power-sensitive systems.  

### **Features:**  
- **Low Power Consumption:**  
  - Operates at 120µA (typical) quiescent current  
  - Shutdown mode reduces current to ≤1µA  
- **Slew-Rate Limited for Reduced EMI:**  
  - Minimizes interference in communication lines  
- **Enhanced ESD Protection:**  
  - ±15kV protection on driver outputs and receiver inputs  
- **Wide Common-Mode Voltage Range:**  
  - Allows ±7V on receiver inputs for noise immunity  
- **Thermal Shutdown Protection:**  
  - Prevents damage from excessive power dissipation  
- **Compatible with RS-485 and RS-422 Standards**  
- **Half-Duplex Communication Support**
