The 70 mV receiver hysteresis provides noise margin on long cable runs without external filtering. This part is suited for industrial automation, motor drives, and building automation where robust differential signaling over twisted-pair cabling is required.
Housed in an 8-SOIC package (0.154" width, 3.90 mm body).
Yes, the SN65HVD1474D is a full-duplex transceiver, meaning it can transmit and receive simultaneously over separate twisted pairs.
It is not a 5V-supply part, but the RS-485 bus pins tolerate common-mode voltages beyond the supply — verify bus pin absolute maximum ratings in the datasheet for 5V logic interface on the bus side.
Within the same 65HVD1474 base number, the SN65HVD1474D is the tube-packaged variant. The tape-and-reel version (SN65HVD1474DR) shares the same die and footprint. For a different data rate, the SN65HVD1472 (half-duplex, 250 kbps) or SN65HVD1476 (full-duplex, 50 Mbps) are in the same family but check pin compatibility — the half-duplex variants use a different pinout for the driver enable.
