Product details

RS485 transceiver built for automotive and industrial bus lines

The Texas Instruments SN65HVD1780QDRQ1 is a half-duplex RS422/RS485 transceiver in an 8-SOIC package, carrying AEC-Q100 automotive qualification. It handles one driver and one receiver on a single differential bus pair, with the 50 mV receiver hysteresis that helps keep noise from long cable runs from triggering false start bits.

115 Kbps — enough for most sensor and actuator networks

The data rate caps at 115 Kbps. That is fine for PLC-to-drive links, HVAC zone controllers, battery-monitor polling, or any Modbus RTU network running at 9600 or 38400 baud. If your design needs 1 Mbps or higher, this is not the part — look at the SN65HVD17xx family instead. But for the bulk of industrial fieldbus and automotive body-electronics traffic, 115 Kbps leaves margin.

Frequently asked questions

What is the data rate of SN65HVD1780QDRQ1?

The data rate is 115 Kbps, which covers standard industrial fieldbus speeds like 9600 and 38400 baud as well as Modbus RTU.
