SN65HVD30: Can SN65HVD30 support half-duplex?

Part Number: SN65HVD30
Other Parts Discussed in Thread: SN65HVD10

Hi Team,

Can SN65HVD30 support half-duplex?  If so, could you share a diagram to guide the connection? Thanks!

  • You can just connect the A/Y and B/Z pins together. Compare the internal schematics of the SN65HVD30 and the SN65HVD10:

  • Hi Rayna,

    So if a full duplex device has enables you can wire it as a half-duplex by connecting A to Y and B to Z directly.

    For devices like the SN65HVD30 - you can't because the driver is always active and will constantly be driving so they must remain as full duplex. 

    Why is your customer trying to use a full-duplex device as a half duplex? 

    Best,
