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
