Part Number: THVD1500 Tool/software: Hi,
My customers before are using 485 transceiver from competitors and are used to add 10kohm pull up resistor on A pin and 10kohm pull down resistors on B pins. Currently they turned to THVD1500 and found that 10kohm…
Part Number: THVD1500 Tool/software: Hi expert，
Why there isn't a pull up resistor for the D pin? And there is a 10k pull up resistor for R pin?
If customer set a 10k pull up resistor in D pin, what will be effect, can you help evaluate it?
Part Number: THVD1500 Other Parts Discussed in Thread: TIDA-01630 Hi,
My question is regarding qualifications of THVD1500 device, or in general RS485 interface devices from TI with regards to conducted and radiated emissions.
It seems like on RS485, the…
Part Number: THVD1500 Hi team
What's the logic side input(D pin) capacitance value? Typical values would be ok, we need this value to evaluate the pull-down resistors, thanks!
Part Number: THVD1500 Hello guys,
One of my customers is considering using THVD1500 or so on for their new products. At this moment, they have the following question. Could you please give me your reply?
Q. I think the following description case in RS485…
Part Number: THVD1500 Hi Team,
My customer is facing a problem when using THVD1500. They set the RL=120ohm and found that the output current, driver allows only 60mA. They think the drive capability is a little low when they are adding more than6 THVD1500…
Part Number: THVD1500 Hi all,
in a RS485 System with 2 nodes, is it possible that one transceiver is supplied with 5V and one transceiver is supplied with 3,3V (withour levelshifter)? I tried this with the THVD1500 and it is working, but i'm not sure…
Part Number: THVD1505 Other Parts Discussed in Thread: THVD1500 , THVD1429 , THVD1510 Team,
just to be sure: THVD1500 can be directly replaced by THVD1505 on an existing PCB designed for THVD1500. Correct? It is 100% backward compatible. Correct?
In fact…
Part Number: THVD1500 Other Parts Discussed in Thread: THVD1406 Hi Team,
My customer use THVD1500 in their project.
The customer has found a waveform anomaly when the system with 20 unit load( 12Kohm ).
Below is the schematic and test waveform, could you…
