SN65HVD3082E: Bus input impedance

Hi Team,

My customer is planning to replace SN65HVD3082E that used at MPed projects by THVD1520 and R&D is making comparison table. The parameter of "Bus imput impedance" can be found at THVD1520's datasheet, but it cannot be found at SN65HVD3082E's. Could team help to provide this parameter?

Thanks very much.
