The SN65HVD257DR is a robust, high-performance CAN (Controller Area Network) transceiver module designed and manufactured by Texas Instruments. This device is specifically engineered to facilitate communication in automotive and industrial applications, providing a critical bridge between the CAN protocol controller and the physical two-wire CAN bus.
Key Features
- Bus-Pin ESD Protection: Exceeds 16 kV HBM (Human Body Model), ensuring durability and reliability in harsh environments.
- High-Speed Operation: Capable of transmitting and receiving at speeds of up to 1 Mbps, making it suitable for high-speed CAN systems.
- Differential Output: The device can drive a differential bus with voltage levels that comply with the ISO 11898 standard.
- Silent Mode: When disabled, the SN65HVD257DR enters a low-power mode where the transmitter is switched off, allowing the device to listen on the bus without contributing to bus traffic.
- Thermal Shutdown Protection: Incorporated to prevent device failure due to excessive temperature.
- Open-Circuit Fail-Safe Design: Ensures a known safe-bus output state when the bus is floating (disconnected).
- Glitch-Free Power-Up and Power-Down: For additional protection against bus disturbances.
