Other Parts Discussed in Thread: SN65LBC180A, SN65LBC176A

Customer want to use SN65LBC180A of Half-duplex operation.

Is there a way of Half duplex circuit?

 

【Additional information】

・Customer was using SN65LBC180A (Full duplex).

　Suddenly, latest board must operate Half duplex. 

・Customer request is 2-way following

　①Half duplex RS485 that Pin compatible with SN65LBC180A.

　② If ① nothing, using SN65LBC180A on Half duplex.

　　（Is it OK for Y-A and Z-B short?）

・Z-pin and Y-pin is open

 

Best regards,

    Hello Satoshi-san,

    There are many different options available for half-duplex transceivers. I would recommend first taking a look at the SN65LBC176A, which is very similar to the device currently being used. (It does not use the exact same pinout, but instead uses an 8-pin footprint that is more common for half-duplex devices.) It is also OK to operate any full-duplex device in a half-duplex application by tying the corresponding driver and receiver pins together (as you have mentioned). Please let me know if you have any further questions.

    Regards,
    Max
