    Part Number: THVD8000 Other Parts Discussed in Thread: THVD1505 , , TIDA-01171 , SN65HVD96 Hi, looking to replace SN65HVD96DR with THVD1505 and THVD8000, I was wanting to check, What is the typical distance achievable with these devices on non-twisted…

  • RS-485

    TI Thinks Resolved
    Other Parts Discussed in Thread: SN65ALS176 , THVD1505 , THVD1400 Hi everyone, SN65ALS176 is declared to work properly between 4.75V and 5.25V If I suplly the transceiver with a power supply of 4.5-5.5V, what kind of malfunction or degradation should…

  • RE: SN65HVD06: Can I connect A pin of one SN65HVD06 to B pin of another SN65HVD06?

    Hi Rachel, Electrically it is fine to connect the devices in this way. The Maximum differential output voltage for SN65HVD06 's driver is Vcc and the receiver can tolerate +-12V differentials. However, the data on the R pins would be inverted in this…
