series introduction

# SN65HVD233 Product Series Introduction

## 1. Overview
The SN65HVD233 is a highly versatile and reliable product series designed for use in Controller Area Network (CAN) applications. CAN is a widely adopted serial communication protocol in various industries, including automotive, industrial automation, and aerospace, due to its robustness, high - speed data transfer capabilities, and multi - master communication features. The SN65HVD233 series serves as a CAN transceiver, which is a crucial component that interfaces the CAN protocol controller with the physical bus.

## 2. Key Features

### 2.1 Electrical Characteristics
- **Wide Supply Voltage Range**: The SN65HVD233 operates over a wide supply voltage range, typically from 4.5V to 5.5V. This flexibility allows it to be easily integrated into different power supply systems, accommodating various design requirements.
- **Low Power Consumption**: It is designed with low - power operation in mind. In standby mode, the power consumption is extremely low, making it suitable for battery - powered applications where energy efficiency is a critical factor. This feature helps to extend the battery life of the overall system.
- **High - Speed Data Transfer**: The transceiver supports high - speed data rates up to 1 Mbps. This enables fast and efficient communication between nodes on the CAN bus, ensuring timely data exchange in real - time applications.

### 2.2 Robustness and Protection
- **Fault Protection**: The SN65HVD233 is equipped with comprehensive fault protection mechanisms. It can withstand short - circuits to battery, ground, and other nodes on the bus. This protection ensures the reliability of the transceiver and the entire CAN network, even in harsh operating environments where electrical faults may occur.
- **ESD Protection**: It offers excellent Electrostatic Discharge (ESD) protection on both the CAN bus pins and the transceiver's input/output pins. This protection helps to prevent damage from static electricity, which is a common cause of component failure in electronic systems.

### 2.3 Compatibility
- **CAN Protocol Compatibility**: The SN65HVD233 is fully compliant with the ISO 11898 - 2 standard, which is the international standard for high - speed CAN communication. This ensures seamless integration with other CAN - compliant devices, allowing for easy interoperability in a multi - vendor environment.

## 3. Functional Block Diagram and Operation

### 3.1 Block Diagram
The SN65HVD233 consists of several key functional blocks, including a transmitter, a receiver, a power supply regulator, and protection circuits. The transmitter takes the digital signals from the CAN protocol controller and converts them into differential signals suitable for transmission over the CAN bus. The receiver, on the other hand, receives the differential signals from the bus and converts them back into digital signals for the CAN controller.

### 3.2 Operation Modes
- **Normal Mode**: In normal mode, the transceiver is fully operational, allowing data to be transmitted and received between the CAN controller and the bus. The transmitter and receiver are both active, and the device is ready to participate in the CAN network communication.
- **Standby Mode**: In standby mode, the transceiver enters a low - power state. The transmitter is disabled, and the receiver is put into a low - power listening mode. This mode is useful for conserving power when the device is not actively involved in communication.

## 4. Applications

### 4.1 Automotive Industry
- **Vehicle Control Systems**: In modern vehicles, the SN65HVD233 can be used in various control systems such as engine control units (ECUs), transmission control units (TCUs), and body control modules (BCMs). These systems need to communicate with each other in
