SN65HVD1782DR in TI SN65HVD CAN / RS-485 Family
The SN65HVD1782DR belongs to the Texas Instruments SN65HVD178x family of RS-485 transceivers designed for industrial applications requiring extreme bus-fault protection. These devices are engineered to withstand high-voltage transients and direct short circuits to power supplies up to 70V. Operating from a 3.3V to 5V supply, they provide a robust physical layer for differential data signaling in harsh electrical environments where standard transceivers might fail due to overvoltage conditions or wiring errors.
Variants in This Sub-Family
Variants within the SN65HVD178x sub-family are primarily distinguished by their maximum data rates and driver characteristics. Some members are optimized for high-speed transmission up to 10 Mbps for short-haul links, while others feature slew-rate limiting to minimize electromagnetic emissions and reflections on long, unterminated cables at lower baud rates. Package options vary between SOIC and PDIP to accommodate different assembly requirements.
