TIDA-01090: full duplex mode

Part Number: TIDA-01090
Other Parts Discussed in Thread: NA555, SN65HVD3082E

Dear team,

Customer are looking for full duplex mode solution and find TIDA-01090 from TI website.

But this app note is half duplex mode. Could we design with two set of TIDA-01090 together for full duplex mode application?

If yes, did we need 4*NA555 for full duplex application? Thanks.

Regards,

Ben

    Ben,

    I'd like to just ask a few questions so that I better understand this application.

    • Is there a particular RS-485 part you're looking to use for this (since the SN65HVD3082E is only half-duplex)?
    • Are you looking to use a two-wire full-duplex interface or a four-wire interface?

    Best,

    Danny
