Description and Introduction

3.3V Low Power Half-Duplex RS-485 Transceivers with 10Mbps Data Rate The SP3481EP is a low-power transceiver manufactured by SIPEX (now part of Microchip Technology). It is designed for RS-485 and RS-422 communication applications.  

### **Specifications:**  
- **Supply Voltage:** 3.3V  
- **Data Rate:** Up to 10 Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Half-Duplex Communication**  
- **Low Power Consumption:**  
  - **Active Current:** 300 µA (typical)  
  - **Shutdown Current:** 1 µA (typical)  
- **ESD Protection:** ±15 kV (Human Body Model)  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The SP3481EP is a 3.3V RS-485/RS-422 transceiver optimized for low-power applications. It features a slew-rate-limited driver to minimize EMI and reduce reflections in improperly terminated networks. The device is suitable for industrial control, instrumentation, and point-of-sale systems.  

### **Features:**  
- **3.3V Operation**  
- **Enhanced ESD Protection**  
- **Slew-Rate Limited for Reduced EMI**  
- **1/8 Unit Load (Allows up to 256 Nodes on a Bus)**  
- **Low-Power Shutdown Mode**  
- **Compatible with TIA/EIA-485-A Standards**  
- **Industrial-Grade Reliability**  

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

Application Scenarios & Design Considerations

3.3V Low Power Half-Duplex RS-485 Transceivers with 10Mbps Data Rate

Alternative Part Number

  • MAX3485EPA+ --: Pin-compatible 3.3V RS-485 transceiver with the same 8-pin DIP footprint and similar drive strength, widely available and a common drop-in replacement for the SP3481.
  • SN65HVD3082EP --: 3.3V RS-485 transceiver in 8-pin PDIP with comparable data rate and bus characteristics, offering good availability and similar electrical behavior.
  • ISL8485EIP --: 3.3V RS-485/RS-422 transceiver in 8-pin DIP with equivalent pinout and function, suitable as an alternative when the original Sipex part is unavailable.
  • MAX3485ESA --: Pin-compatible 3.3V RS-485 transceiver with the same 8-pin SOIC footprint and similar drive strength, widely available and a common drop-in replacement.
  • SN65HVD3082EDR --: 3.3V RS-485 transceiver in SOIC-8 with comparable data rate and ESD performance, well stocked and often used to replace SP3481-class parts.
  • ISL8485EIBZ --: 3.3V half-duplex RS-485 transceiver in SOIC-8 with similar electrical characteristics and a different series naming, making it easy to distinguish from the original.
