The 5 V nominal supply is a hard constraint: if your microcontroller or UART runs at 3.3 V, you will need level translation on the logic-side pins (RO, DI, RE, DE). The part itself is not 3.3 V tolerant on the supply. ## Package and rework — 8-SOIC with standard pitch No thermal pad or exposed paddle to worry about — just standard 0.050-inch pitch land pattern.","metaTitle":"SN65HVD1786DG4 RS-485/RS-422 Transceiver, 1 Mbps, 8-SOIC","metaDescription":"Texas Instruments SN65HVD1786DG4 half-duplex RS-485/RS-422 transceiver. 1 Mbps data rate, 4.5V-5.5V supply, -40°C to 105°C.

Both share the same base RS-485/RS-422 transceiver function, 1/1 driver/receiver count, half-duplex protocol, and 8-SOIC package. The DG4 suffix often denotes lead-free / RoHS-compliant plating. For a pin-compatible second source within the same family, the SN65HVD1786D is the closest drop-in alternative, but verify the specific compliance marking for your assembly house's requirements."},{"question":"Is SN65HVD1786DG4 compatible with 3.3V logic?","answer":"The logic-side pins (RO, DI, RE, DE) are referenced to that supply rail, so they are not 3.3 V tolerant. You will need a level translator or a 5 V-tolerant UART on the microcontroller side to interface directly."},{"question":"What is the maximum data rate of SN65HVD1786DG4?","answer":"The SN65HVD1786DG4 supports data rates up to 1 Mbps.
