Description and Introduction

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers The MAX489EEPD is a low-power transceiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX489EEPD  
- **Type:** RS-422/RS-485 Interface IC  
- **Operating Voltage:** +4.75V to +5.25V  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 14-Pin PDIP (Plastic Dual In-Line Package)  
- **ESD Protection:** ±15kV (Human Body Model)  

### **Descriptions:**
- The MAX489EEPD is a low-power transceiver designed for RS-422 and RS-485 communication.  
- It features a single driver and receiver, making it suitable for half-duplex communication.  
- The device operates from a single +5V power supply and is optimized for high-speed data transmission.  
- It includes slew-rate-limited drivers to reduce EMI and minimize reflections in improperly terminated cables.  

### **Features:**
- **Low Power Consumption:** Operates with reduced power for energy-efficient applications.  
- **ESD Protection:** Robust ±15kV protection on driver outputs and receiver inputs.  
- **Slew-Rate Limited Drivers:** Helps reduce EMI and signal distortion.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Half-Duplex Communication:** Supports bidirectional data transmission on a single pair of wires.  
- **Wide Operating Temperature Range:** Suitable for industrial environments (-40°C to +85°C).  

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 differential transceiver in DIP-8, pin-compatible with MAX489 and widely available as a lower-cost alternative.
  • ADM485ANZ --: RS-485 transceiver in DIP-8 with similar driver/receiver characteristics and ESD protection, suitable drop-in replacement for MAX489EEPD.
  • LTC485CN8 --: Low-power RS-485 transceiver in DIP-8 offering comparable functionality and pinout to the MAX489, useful as a second-source option.
  • ADM489AN --: RS-485 transceiver with the same 14-pin DIP footprint and full-duplex capability, offering equivalent electrical performance to the MAX489.
  • LTC489CN --: Pin-compatible RS-485 transceiver in a 14-pin DIP package with similar driver/receiver characteristics, suitable as a drop-in replacement.
