On a factory-floor RS-485 run with common-mode noise from VFDs, that hysteresis prevents the receiver from chattering on a slow edge or a slightly unbalanced bus idle. It is a practical margin-budget feature, not just a datasheet line. There is no last-time-buy deadline to track, and no forced migration to a different transceiver for the next board spin.","metaTitle":"SN65HVD1781D RS-485/RS-422 Transceiver, 1 Mbps, 3.15-5.5 V","metaDescription":"TI SN65HVD1781D is a half-duplex RS-485/RS-422 transceiver in SOIC-8, rated 1 Mbps, 3.15 V to 5.5 V supply, -40°C to 125°C.
