The SN65HVD1471DR is a full-duplex transceiver supporting RS422 and RS485 protocols, with a single driver and single receiver in the 8-SOIC package.
Supply voltage is 3V to 3.6V, which means this part runs from a 3.3V rail with about 300mV of headroom — no 5V tolerance on the supply side.
The base product number is 65HVD1471, and the family includes variants with different data rates and package options. A direct pin-compatible alternative within the same family would be another 8-SOIC full-duplex transceiver sharing the same pinout, such as the SN65HVD1470D (half-duplex) or SN65HVD1472D (higher data rate) — but confirm the specific pinout and function before substituting.
The SN65HVD1471DR is ROHS3 compliant. Texas Instruments typically provides RoHS and REACH declarations;
