Description and Introduction

Low Power Half-Duplex RS-485 Transceivers The SP485ES is a low-power RS-485/RS-422 transceiver manufactured by SIPEX (now part of Microchip Technology).  

### **Specifications:**  
- **Supply Voltage:** 4.75V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 10Mbps  
- **Driver Output Current (Short-Circuit):** ±60mA  
- **Receiver Input Impedance:** ≥12kΩ  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Half-Duplex Communication**  
- **Low Power Consumption:**  
  - **Shutdown Current:** <1µA  
  - **Quiescent Current:** <1mA  

### **Descriptions:**  
- The SP485ES is designed for bidirectional data communication on multipoint bus transmission lines (RS-485/RS-422).  
- It features a slew-rate-limited driver to reduce EMI and minimize reflections in improperly terminated networks.  
- The device includes thermal shutdown protection and failsafe receiver inputs (open, shorted, or terminated).  

### **Features:**  
- **Enhanced ESD Protection:** Protects against electrostatic discharge.  
- **1/8 Unit Load:** Allows up to 256 transceivers on the bus.  
- **Slew-Rate Limited Driver:** Reduces EMI and signal distortion.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Low-Power Shutdown Mode:** Consumes less than 1µA when disabled.  
- **Industrial-Grade Operation:** Suitable for harsh environments.  

For detailed electrical characteristics and application notes, refer to the official SIPEX (Microchip) datasheet.

- **Package Type:** 8-pin SOIC  

### **Descriptions:**  
- The SP485ES is designed for balanced data transmission in RS-485 and RS-422 applications.  
- It features a low-power shutdown mode, making it suitable for battery-powered systems.  
- The device includes thermal shutdown protection and is compatible with industry-standard RS-485/RS-422 protocols.  

### **Features:**  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to ±15kV.  
- **Wide Common-Mode Voltage Range:** -7V to +12V for robust noise immunity.  
- **Driver Output Short-Circuit Protection:** Prevents damage during faults.  
- **Thermal Shutdown:** Safeguards the device from overheating.  
- **Low EMI:** Meets FCC and CE standards for electromagnetic interference.  
- **Industrial-Grade Reliability:** Operates in harsh environments (-40°C to +85°C).  

This information is strictly based on the manufacturer's datasheet for the SP485ES by SIPEX.
