This is a single-driver, single-receiver half-duplex transceiver for RS-422 and RS-485 networks. The 115 kbps data rate is the ceiling. The 50 mV of receiver hysteresis cleans up noise on longer cable runs. ## 5 V supply only — not a 3.3 V part If your system is 3.3 V only, this part will not work — you would need a 3.3 V RS-485 transceiver like the SN65HVD1781 or a level shifter. On a mixed-voltage board, the logic inputs are 5 V tolerant, but the VCC must be 5 V for the driver to meet the RS-485 output levels. ## Through-hole PDIP — for prototyping and legacy boards Packaged in an 8-pin PDIP (0.300 inch body), this is a through-hole part. It is a natural fit for breadboard prototyping, point-to-point wiring, and repairing older equipment where the PCB layout expects a DIP socket. ## Temperature grade: industrial, not automotive It is not AEC-Q100 qualified, so it is not the right choice for under-hood automotive or other high-reliability automotive applications unless you do your own qualification.","metaTitle":"SN65HVD1785P RS-485 Transceiver, 115 kbps, 8-PDIP","metaDescription":"TI SN65HVD1785P half-duplex RS-422/485 transceiver, 115 kbps data rate, 4.5-5.5 V supply, -40 to 105°C, 8-PDIP.
