  SN65HVD75: Output Architecture of Receiver Inputs

  Part Number: SN65HVD75 Hi Team, For the receiver inputs, does it have push-pull output? It's found that there is leakage path when R pin is pulled up to another 3.3V power supply if Vcc is powered off earlier than 3.3V, so I wondering there should...

  RE: WEBENCH® Tools/SN65HVD75: TVS selection of SN65HVD75

  Hi, A slightly larger means the peak voltage might be 1V to 2V higher than the abs max. Based on the datasheet, 19V is the clamping voltage for only 1A current. Regards, Hao

  RE: SN65HVD75: PCB trace impedance

  Hi Randy, Generally it is best to route A/B as differential signals with characteristic impedance equal to the impedance of the cabling used. For short PCB traces, though, this typically is not critical. (You could compare the propagation delay of the...

  RE: SN65HVD75: Cabling topologies and method

  Karthik, I think common mode choke are commonly used for signal's transient behavior, while the ground potential difference is a DC bias. Here is an app note for common mode choke. www.ti.com/.../slla271.pdf Regards, Hao

  RE: SN65HVD75: Schematic review

  Tony, The pull up/down are used to generate a bias on bus. In this case, both the fail-safe and non-fail-safe devices will output a H in fault conditions. Without pull up/down, the fail-safe devices can still generate a H and the non-fail-safe devices...
