The 130 mV hysteresis on the receiver input rejects noise on long twisted-pair cables better than the 50 mV typical of older transceivers, reducing bit errors in electrically noisy environments like factory floors or vehicle power trains.","metaTitle":"TI SN65HVD21MDREP RS-485 Transceiver, 5 Mbps, -55 to 125°C","metaDescription":"Texas Instruments SN65HVD21MDREP half-duplex RS-422/RS-485 transceiver. 5 Mbps data rate, 130 mV hysteresis, -55 to 125°C range.
