SN65HVD1781AQDRQ1 in TI SN65HVD CAN / RS-485 Family
The SN65HVD178x-Q1 series by Texas Instruments is a family of fault-protected RS-485 transceivers designed for robust communication in harsh industrial and automotive environments. These AEC-Q100 qualified devices feature high levels of protection against bus-pin faults, including overvoltage protection up to ±70V and significant ESD resistance. They are specifically engineered to maintain data integrity in the presence of large common-mode voltages and electrical noise, making them a standard choice for reliable differential signaling systems.
Variants in This Sub-Family
Variants within the SN65HVD178x-Q1 sub-family typically differ in their maximum supported data rates and electrical characteristics tailored for specific EMI profiles. While the 1781 version is optimized for speeds up to 1 Mbps, other members of the broader HVD17xx line may offer different driver output voltages or power consumption profiles to balance signal distance against power efficiency and electromagnetic compatibility requirements in diverse system layouts.
