  • SN65HVD11: Protocols used in RS-485

    TI Thinks Resolved
    Part Number: SN65HVD11 I know there is no standard / defined Protocol for RS-485, but: Is there some "generally / most used" in industry? Is using RS-232 (Start, 7/8 bits, STOP) widely used. Is using MODBUS OK? Any suggestions appreciated

  • SN65HVD11: about SN65HVD11D A/B port shorted current

    Resolved
    Part Number: SN65HVD11 I'm using the HVD11 to drive 100ft of wire and associated emi filter capacitance to ground (7Mbps Manchester encoded format). I want to make sure that output waveform does not become too rounded-off due to effects of part's output…

  • SN65HVD11: 1Hz signal transfer through Ethernet cable

    TI Thinks Resolved
    Part Number: SN65HVD11 Hi Supporter My customer transfer 1Hz signal between two boards. One piece SN65HVD11 on each board. Two boards are connected by Ethernet cable through RJ45. If GND of two boards are not connected well, could SN65HVD11 still work…

  • SN65HVD11: Va and Vb both stay around 0.9V

    Resolved
    Part Number: SN65HVD11 In a 3V3 system, When DE = 0, Va and Vb both stay at around 0,9V, even with 499Ohm failsafe biasing resistors and 120Ohm Terminating resistor. The SN65HVD11 works fine when switching ones and zeros, when DE = 1 Seems that both…

  • SN65HVD11: Voltages of INTERNAL vs External Failsafe Biasing

    TI Thinks Resolved
    Part Number: SN65HVD11 The newer RS-485 devices claim to have built in failsafe circuitry. So if NO external biasing resistors are used, what is the voltage on the A/B lines. On the other hand, if the master has say 1K Pull-up/down for bias, and 120…

  • SN65HVD11: about SN65HVD11D A/B port shorted current

    Resolved
    Part Number: SN65HVD11 hi dear supporting team, as for SN65HVD11D, because it is at the brd edge which interface to external, if in lightening stroke, suppose the A/B prot pin is shorted to GND, could we gurantee the shorted current to GND be smaller…

  • SN65HVD11: Applied in multi-voltage networks

    Resolved
    Part Number: SN65HVD11 Hi, Does SN65HVD11 which has failsafe function need failsafe bias network in multi-voltage networks? Could SN65HVD11 work regularly when the voltage on pin A or pin B is 4.4V? Schematic diagram is as below, Thanks, Walsh
