Description and Introduction

3.3V Low Power Quad RS-485/RS-422 Line Drivers The SP3486ET is a low-power RS-485/RS-422 transceiver manufactured by SIPEX (now part of Microchip Technology).  

### **Specifications:**  
- **Supply Voltage:** 3.3V  
- **Data Rate:** Up to 10 Mbps (Mega bits per second)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Low Power Consumption:** Typically 300 µA in shutdown mode  
- **Half-Duplex Communication**  
- **ESD Protection:** ±15 kV (Human Body Model)  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- The SP3486ET is designed for bidirectional data communication on multipoint bus transmission lines (RS-485/RS-422).  
- It features a low-power shutdown mode for power-sensitive applications.  
- The device is compatible with 3.3V systems and supports high-speed data transmission.  

### **Features:**  
- **3.3V Operation**  
- **Enhanced ESD Protection**  
- **1/8 Unit Load (Allows up to 256 Transceivers on the Bus)**  
- **Driver Output Short-Circuit Protection**  
- **Receiver Open-Circuit Fail-Safe**  
- **Thermal Shutdown Protection**  

The SP3486ET is commonly used in industrial control, instrumentation, and networking applications.

Alternative Part Number

  • MAX3486ESA --: Pin-compatible RS-485 transceiver with the same 3.3V supply and half-duplex operation, widely available and a direct functional drop-in.
  • SN75176BDR --: Industry-standard RS-485 differential bus transceiver in SOIC-8, functionally equivalent for most half-duplex applications though rated at 5V.
  • ISL8485EIBZ --: 3.3V RS-485/RS-422 transceiver in SOIC-8 with similar data rate and pinout, suitable as a second-source alternative.
  • MAX3486ESA+ --: Pin-compatible 3.3V half-duplex RS-485 transceiver with the same 8-pin SOIC footprint and similar data rate, widely available and a direct functional drop-in.
  • SN65HVD3082EDR --: 3.3V RS-485 transceiver in SOIC-8 with comparable speed and drive capability, well-stocked and often used as a replacement for SP3486-class parts.
