The 115 kbps maximum data rate places this part in the slow-to-moderate speed tier for RS-485. It is a good fit for fieldbus protocols like Modbus RTU at 9600 or 19200 baud, or for simple sensor polling loops where cable length rather than throughput is the constraint. At this signaling rate the bus can comfortably run several hundred meters without special termination or repeater concerns. The 105°C upper limit is enough for most engine-bay-adjacent zones but not for direct exhaust or brake-system mounting.","metaTitle":"SN65HVD1794DR RS-485/RS-422 Transceiver, Half-Duplex","metaDescription":"TI SN65HVD1794DR half-duplex RS-485/RS-422 transceiver. 115 kbps data rate, 4.5-5.5 V supply, -40 to 105°C.

The key difference is the data rate: the SN65HVD1794DR is rated for 115 kbps, while the SN65HVD1792DR supports a higher signaling rate.
