Description and Introduction

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers The MAX487ECSA 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  
- **Part Number:** MAX487ECSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Supply Voltage (VCC):** +4.75V to +5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Protocol Support:** RS-485, RS-422  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Quiescent Current (Standby):** 120µA (max)  
- **Receiver Input Impedance:** ≥12kΩ  

### **Description:**  
The MAX487ECSA is a low-power, slew-rate-limited transceiver designed for RS-485 and RS-422 communication. It features reduced EMI (Electromagnetic Interference) due to its slew-rate-limited driver, making it suitable for noise-sensitive applications. The device operates with a single +5V supply and includes thermal shutdown protection.  

### **Features:**  
- Low-power operation (120µA max quiescent current)  
- Slew-rate-limited driver for reduced EMI  
- Half-duplex communication  
- Thermal shutdown protection  
- 1/8-unit load allows up to 128 transceivers on the bus  
- -7V to +12V common-mode input voltage range  
- Short-circuit current limiting  

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

  • SN75176BDR --: Industry-standard RS-485/RS-422 transceiver, pin-compatible with MAX487 in SOIC-8, widely available and cost-effective.
  • SP485ECN-L --: Direct functional equivalent RS-485 transceiver with ESD protection, same 8-pin package and pinout, good drop-in alternative.
  • ISL8487EIBZ --: Low-power RS-485/RS-422 transceiver with similar data rate and pinout, suitable replacement when MAX487 is unavailable.
  • ST485ECDR --: Low-power RS-485/RS-422 transceiver with similar data rate and pinout, suitable replacement when MAX487ECSA is unavailable.
