Full-duplex operation means simultaneous transmit and receive on separate wire pairs, which halves the cable count for bidirectional links compared to half-duplex parts that need direction toggling.
70 mV receiver hysteresis — noise margin for long cable runs
The receiver hysteresis is specified at 70 mV, which provides a clean switching threshold on a noisy bus. In practice, this means the part can tolerate a few hundred millivolts of ground shift or coupled noise without chattering the output — useful when the transceiver sits at the end of a 100-meter RS-485 drop in a factory floor environment.
Package and footprint — 10-VSSOP
Housed in a 10-VSSOP (also described as 10-TFSOP, 10-MSOP with 0.118" width, 3.00 mm body), the SN65HVD1470DGSR is a surface-mount device.
