### **Descriptions:**  
The MAX481CPA is a low-power, slew-rate-limited RS-485/RS-422 transceiver designed for half-duplex communication. It features reduced EMI and reflections due to its slew-rate-limited driver, making it suitable for noise-sensitive applications. The device includes one driver and one receiver, with built-in protection against electrostatic discharge (ESD).  

### **Features:**  
- Low-power operation (120µA quiescent current)  
- Slew-rate-limited driver for reduced EMI  
- Half-duplex communication  
- ESD protection (±15kV)  
- Thermal shutdown protection  
- Short-circuit current limiting  
- Compatible with RS-485 and RS-422 standards  
- Receiver input hysteresis for noise immunity  

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

### **Specifications:**  
- **Supply Voltage Range:** +4.5V to +5.5V  
- **Low Quiescent Current:** 120µA (typical)  
- **Data Rate:** Up to 2.5Mbps  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Receiver Input Impedance:** 12kΩ (minimum)  
- **Driver Output Voltage Swing:** ±5V (with external termination)  
- **Common-Mode Input Voltage Range:** -7V to +12V  

### **Descriptions:**  
The MAX481CPA is a low-power, RS-485/RS-422 compliant transceiver designed for half-duplex communication. It features a slew-rate-limited driver to reduce EMI and minimize reflections in improperly terminated cables. The device includes fail-safe circuitry to ensure a logic-high receiver output when inputs are open or shorted.
