  • 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…

  • TIDA-01090: Tida-01093 solution, two acquisition chips communicate through IIC. If the two acquisition chips have different IIC addresses, can they communicate directly according to different address addressing instead of switching channels?

  • RE: SN65HVD3082E: How control direction automatically?

    Hello Mounish, One possible solution is this reference design that can be used with any RS-485 driver: ti.com/tool/TIDA-01090 If you can adjust parts, THVD1406 and THVD1426 also have auto-direction control built in. Best, Ethan

  • RE: THVD1406: Missing beginning of response if receiver can't enable fast enough?

    Hi Franz, For the THVD14x6 family of devices they need to be used at the specified data rate for them to work properly. That being said - auto-direction can be achieved with any part with enables through the addition of a timer circuit - as shown…

  • RS-485 with automatic direction control.

    Resolved
    Other Parts Discussed in Thread: TIDA-01090 Some my customers (2 in last week) see that TI updates their interfaces product lines and ask me about RS-485 with automatic direction control like MAX13488/MAX13487. We know that TI have reference design HOWTO…

  • RE: ISO1500: Auto-direction control circuit for ISO1500

    Resolved
    Hi Charles: Thanks for posting on E2E. This is a very interesting way to achieve auto-direction control in RS-485 communication. Theoretically, this circuit works. In transmit mode, logic zero is achieved by driving the RS-485 bus low while…

  • RE: THVD1505: Can RE_ and DE be terminated with resistors in slave mode?

    Resolved
    Hi Lauren, So RS-485 transceivers only implements the Physical layer (as RS-485 is a PHY only standard - data-link/network level control is not defined so it is up to system designer to determine what protocol is needed) - so communication is controlled…

  • RE: SN65HVD72: SN65HVD72D : Auto Transreceiver through single GPIO

    Gagandeep, The simplest solution would be to place a pull-up resistor on the "A" line, a pull-down resistor on the "B" line, tie the "D" input low, and then provide your data signal to the "DE" input instead. This way there would be a couple of different…
