SN65HVD3082E: Bus input impedance

Part Number: SN65HVD3082E
Other Parts Discussed in Thread: THVD1520

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.

    The RS-485 standard specifies that a compliant driver must be able to drive 32 unit loads, where one unit load represents a load impedance of about 12 kΩ.

    Both the SN65HVD3082E and the THVD1520 are one eighth of a unit load, i.e., they have an input impedance of 96 kΩ.
