SN65HVD3082E: the differential output current value when Vcc and Load changes.

Shinichi Inoue

Part Number: SN65HVD3082E

Dear Specialists,

My customer'd like to obtain a graph of the differential output current value when Vcc changes.

Data sheet P.8 Figure 6-5. Driver Differential Output Voltage versus Driver Output Current only describes Vcc = 5V.


They want a graph with the characteristics when Vcc = 5.5V and 4.5V.

The graphs of other company is shown for reference.( The other maker's product)

If possible, it would be nice if there was data when Vcc = 4V in addition.

They are investigating differential output current change and Vcc. 

I appreciate your great help in advance.

Best regards,

Shinichi

    Shinichi,

    The differential output current is the differential output voltage divided by the load resistance, VOD/RL. Regardless of the VCC, it will depend on the VOD voltage, and VCC will limit the differential voltage output range, but it won't directly affect the differential output current. 

    Does this make sense?

    Regards,

    Hi Eric,

    Thank you for your reply.

    I understand the differential output current is related with VOD/RL.

    I'll share this information with the customer.

    Also, do you have any additional graph like listed above.

    If the customer has an additional question, I consult you again.

    I appreciate your great help and cooperation.

    Best regards,

    Shinichi

    Inoue-san,

    I don't believe we have a similar graph with multiple supply voltages and load resistances readily available. But again, the graph is just visualizing VOD/RL = IO.

    Hi Eric,

    Thank you for your reply.

    I understand there is no graph with multiple supply voltages and load resistances.

    I'll ask the customer to consider VOD/RL.

    I appreciate your great help and cooperation.

    Best regards,

    Shinichi
