Description and Introduction

±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers The MAX481EEPA+ is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX481EEPA+  
- **Type:** RS-485/RS-422 Transceiver  
- **Supply Voltage Range:** +4.75V to +5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Quiescent Current:** 120µA (typical)  
- **Shutdown Current:** 0.1µA (typical)  

### **Description:**  
The MAX481EEPA+ 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 fail-safe circuitry to ensure a logic-high receiver output when inputs are open or shorted.

### **Features:**  
- Low-power operation (120µA quiescent current)  
- Slew-rate-limited for reduced EMI and reflections  
- Operates from a single +5V supply  
- -7V to +12V common-mode input voltage range  
- Thermal shutdown protection  
- Half-duplex communication  
- Compatible with RS-485 and RS-422 standards  
- ESD protection on bus pins (±15kV)  

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

Application Scenarios & Design Considerations

±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers

Alternative Part Number

  • SN75176BP --: Industry-standard RS-485/RS-422 transceiver, pin-compatible with MAX481 in DIP-8, widely available and cost-effective.
  • ADM485ANZ --: Low-power RS-485 transceiver with similar driver/receiver characteristics and DIP-8 pinout, suitable drop-in replacement.
  • LTC485CN8 --: Low-power RS-485 transceiver with comparable speed and DIP-8 footprint, good alternative when MAX parts are unavailable.
  • ST485BN --: RS-485/RS-422 transceiver in DIP-8 offering comparable performance and pinout, suitable as a cost-effective drop-in substitute.
