Description and Introduction

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX1487CSA is a 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:** MAX1487CSA  
- **Package:** 8-SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage:** 4.75V to 5.25V  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** 0°C to +70°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Interface Type:** RS-422/RS-485  
- **Supply Current (No Load):** 2.5mA (Typical)  

### **Descriptions:**  
The MAX1487CSA is a low-power, high-speed RS-485/RS-422 transceiver designed for half-duplex communication. It features enhanced slew-rate limiting 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.  

### **Features:**  
- **Half-Duplex Communication**  
- **Slew-Rate Limited for Reduced EMI**  
- **Low Power Consumption**  
- **Thermal Shutdown Protection**  
- **Receiver/Driver Enable Control**  
- **Compatible with RS-485 and RS-422 Standards**  
- **High ESD Protection (±15kV HBM)**  
- **Wide Common-Mode Voltage Range (±7V)**  

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

Application Scenarios & Design Considerations

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers

Alternative Part Number

  • SN75176BDR --: Industry-standard RS-485/RS-422 transceiver, pin-compatible with MAX1487 in SOIC-8, widely available and cost-effective drop-in replacement.
  • SP485ECN-L --: RS-485 transceiver with the same 8-pin SOIC footprint and function as MAX1487, offering comparable data rate and ESD performance.
  • ST485CDR --: Low-power RS-485/RS-422 transceiver in SOIC-8, functionally equivalent to MAX1487 with similar supply voltage and driver characteristics.
  • ADM485ARZ --: Low-power RS-485 transceiver with similar data rate and pinout, direct functional replacement in 8-pin SOIC.
  • ST485ECDR --: Low-power RS-485/RS-422 transceiver in SOIC-8 with comparable electrical characteristics and pinout, suitable as a drop-in alternative.
