The 1/1 driver/receiver count is the standard for a single full-duplex node — one driver for the transmit pair, one receiver for the receive pair. For a production BOM, that means the supply channel stays open through normal distribution without the sourcing scramble that comes with an NRND or obsolete part.","metaTitle":"SN65HVD179D RS-485/RS-422 Transceiver, 25 Mbps, 8-SOIC","metaDescription":"TI SN65HVD179D full-duplex transceiver for RS-485/RS-422. 25 Mbps data rate, 4.5V-5.5V supply, -40°C to 85°C.
