SN65HVD1780DR CAN Transceiver 1/1 Half RS422, RS485
The SN65HVD1780DR is a high-speed, fault-tolerant Controller Area Network (CAN) transceiver from Texas Instruments, designed for robust industrial and automotive communication systems. Built on a robust BiCMOS process, this device supports CAN protocol versions 2.0A/B and CAN FD (Flexible Data Rate) up to 5 Mbps, enabling high-bandwidth data exchange in real-time applications. It operates across a wide supply voltage range of 3V to 5.5V, making it compatible with both 3.3V and 5V systems, while its low quiescent current (5 µA typical in standby mode) enhances energy efficiency for battery-powered devices. The transceiver features integrated protection against electrostatic discharge (ESD) up to ±16 kV (HBM) and ±8 kV (IEC 61000-4-2 contact discharge), ensuring reliability in harsh electromagnetic environments. Its SOIC-8 package (5mm x 6mm) with a -40°C to +125°C temperature range suits automotive under-hood and industrial control applications.
Key Technical Specifications
The SN65HVD1780DR supports differential data transmission with a slew rate of 0.3 V/ns to 2 V/ns, minimizing electromagnetic interference (EMI) while maintaining signal integrity over long cable runs (up to 1,000 meters). It features a dominant timeout function to prevent bus lockup and a thermal shutdown circuit that activates at 165°C to protect against overheating. The device includes a VIO pin for independent logic-level shifting, allowing direct interface with microcontrollers operating at 1.8V to 5.5V. Its receiver input impedance (≥20 kΩ) supports up to 112 nodes on a CAN bus, and the transmitter output voltage swing (1.7V to 3.3V) ensures compatibility with standard CAN transceivers. The transceiver also meets ISO 11898-2 and SAE J2284-5 standards, validating its use in automotive safety-critical systems like engine control units (ECUs) and anti-lock braking systems (ABS).
