The SN65HVD22DR: Rated for 500 kbps data rate, it suits moderate-speed fieldbus links in factory automation, building control, and instrumentation networks where the bus length and node count demand a robust differential interface.
The SN65HVD22DR is a half-duplex RS485 transceiver at 500 kbps. A pin-compatible alternative within the same 8-SOIC footprint would be another TI RS485 transceiver with the same 1/1 driver/receiver count and supply range, such as the SN65HVD3082E — though that part is rated for 200 kbps, not 500 kbps. Confirm the data rate requirement before substituting.
