Description and Introduction

3V Full-Duplex RS-485 Driver and Receiver with enables 14-SOIC -40 to 85 The **SN65HVD33DRG4** is a **3.3V CAN transceiver** manufactured by **Texas Instruments (TEXAS)**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (VCC):** 3.3V ±10%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Data Rate:** Up to **1 Mbps**  
- **Bus Fault Protection:** ±36V  
- **ESD Protection:** ±16 kV (IEC 61000-4-2)  
- **Package:** **SOIC-8**  
- **Interface Type:** **CAN (Controller Area Network)**  
- **Number of Drivers/Receivers:** **1/1**  
- **Common Mode Voltage Range (VCM):** ±12V  
- **Low-Power Standby Mode:** **10 µA (Typical)**  

### **Descriptions:**  
The **SN65HVD33DRG4** is a **3.3V CAN bus transceiver** compliant with **ISO 11898-2** standards. It is designed for **high-speed (up to 1 Mbps) CAN communication** in industrial and automotive applications. The device features **high noise immunity**, **bus fault protection**, and **low-power standby mode**, making it suitable for robust CAN networks.

### **Features:**  
- **3.3V Operation** (compatible with 3.3V microcontrollers)  
- **High-Speed CAN (ISO 11898-2 compliant)**  
- **Thermal Shutdown Protection**  
- **Dominant Timeout Function** (prevents bus lock-up)  
- **Unpowered Node Protection** (does not load the bus when unpowered)  
- **Wide Common-Mode Voltage Range** (±12V)  
- **Low Electromagnetic Emission (EME)**  
- **High Electrostatic Discharge (ESD) Protection**  

This transceiver is commonly used in **automotive, industrial control, and embedded systems** requiring reliable CAN communication.

Application Scenarios & Design Considerations

3V Full-Duplex RS-485 Driver and Receiver with enables 14-SOIC -40 to 85

Alternative Part Number

  • MAX3232ECDE --: Pin-compatible RS-232 transceiver with similar dual-driver/receiver function and wide supply range, widely used as a drop-in alternative.
  • SP3232ECP-L --: RS-232 transceiver offering comparable data rate and ESD protection, suitable replacement for industrial serial interfaces.
  • ST3232ECTR --: Low-power RS-232 transceiver with similar driver/receiver configuration and supply voltage, good second-source option.
  • MAX3232ECPE+ --: Widely used RS-232 transceiver in a different series and vendor; functionally similar interface role and easy to source as a drop-in style alternative for many designs.
