SN65HVD77: Ask about SN65HVD77

Other Parts Discussed in Thread: SN65HVD76

Hello support team,

 

My customer want to know about the current consumption of SN65HVD77 as shown below:

 

Is the chart of "Figure 13. SN65HVD76, SN65HVD77 Supply Current vs Signal Rate" in d/s included the current of "Figure 2. Driver Differential-Output Voltage vs Driver Output Current" in d/s?

 

If yes, the customer want to know the actual resistance value.

 

Your help to be very appreciated.

 

Best regards,

Izumi Maruyama

    Izumi,

    Yes, the supply current in Figure 13 includes the load current. The load resistance is 60Ohm. For more details about power dissipation estimation, you can refer to this blog. Please let me know if you have more questions. Regards,
