Part Number: THVD1426 Other Parts Discussed in Thread: THVD1406 , THVD1450 Hi team,
My customer wants to use THVD1426 to achieve auto-direction contorl for half-duplex RS485.
As you can see, customer needs to use 1x GPIO from MCU to control direction…
Part Number: THVD1426 Tool/software: Hi Team
May I know why left red circle part have Rx waveform(Yellow)?
because in my concept it should only have Tx no Rx waveform.
in above situation RE and SHDN both are pull high.
or it's because…
Part Number: THVD1426 Other Parts Discussed in Thread: THVD1406 Hi team,
My customer wants to use THVD1426 in DOBOT.
Now they don't have enough GPIO to control REn so they plan to use auto-direct function.
Datasheet said user needs to connect both…
Part Number: THVD1426 Tool/software: Hello:
I am using THVD1426DR in one application set up in auto-direction control at 3MBaud. I wanted to test this circuit with the direction being controlled instead by an IC (as an option on our PCB).
I followed…
Part Number: THVD1426 Tool/software: This part is a half duplex RS485 transceiver. When the Driver Data input ( D pin) is low, output A is driven low and output B is driven high.
When the D input goes high, that data sheet says that output A will be…
Part Number: THVD1426 Tool/software: Hi Team,
TX sends data to the device without packet loss.
But the RX sent from the device to our board has an error rate 3~5%, Sometimes it can reach 10% or more.
Is there any design problem in the circuit?

Hi Team,
I have been trying daisy chain an RS485 with the THVD1426 as it has auto direction control. My Baud is 57600. Now the protocol is successful but there is some failure of about 3% I would say. At some…
Part Number: THVD1426 Tool/software: Hello,
We are using the THVD1426DRLR RS-485 transceivers for our application with a 5V supply voltage and a 120Ω, 1/10W termination resistor. Could you please confirm if the 1/10W termination resistor is sufficient…
Part Number: THVD1426 Other Parts Discussed in Thread: THVD1406 Hi Sir,
We suggest customer to design in TI RS485 transceiver THVD1426 with auto direction function.
But customer rejected , and we would like to double confirmed TI for their concern…
Part Number: THVD1426 Other Parts Discussed in Thread: THVD1451 Hello, we have to connect an RS422 device (a sensor) to an RS485 system (data logger).
The connection works in one direction (receive data from the sensor) but not bi-directional, we have…
