It handles the bus-driver and receiver pair for a single differential link, with the receiver hysteresis set at 70 mV to reject line noise without external filtering.
The 14-SOIC footprint is a common, board-friendly package that reflows on a standard profile.
The SN65HVD1470DR and SN65HVD1471DR are both full-duplex RS-485 transceivers from the same TI family. The primary difference is data rate: the 1470 is rated at 400 kbps, while the 1471 supports higher speeds. Pinout and package are the same, so they are drop-in replacements if the system can tolerate the rate difference.
The SN65HVD1470DR is rated for a maximum data rate of 400 kbps. This covers common industrial protocols like Modbus RTU at 115.2 kbps with margin, but is not suitable for 1 Mbps or faster links.
Yes. It is directly compatible with 3.3 V logic and power rails, but cannot be used on a 5 V RS-485 bus without level translation.
