SN65HVD1781DR in TI SN65HVD CAN / RS-485 Family
The SN65HVD1781DR belongs to Texas Instruments' series of fault-protected RS-485 transceivers designed to survive overvoltage conditions in harsh industrial environments. These half-duplex devices integrate internal protection against high-voltage transients and bus contention, making them ideal for long-cable runs where ground potential differences or accidental miswiring are common. They combine standard-compliant signaling with high levels of ESD protection and a wide common-mode voltage range to ensure robust data communication in demanding electrical conditions.
Variants in This Sub-Family
Variants within this sub-family primarily differ based on their maximum data rate and fault protection levels. While the 1781 is optimized for 1 Mbps, related versions may offer higher speeds like 10 Mbps or 20 Mbps at the cost of reduced noise immunity or different power consumption profiles. Package options vary from standard SOIC-8 to smaller VSSOP footprints to meet different PCB density requirements.
