Part Number: THVD1400 Other Parts Discussed in Thread: THS6222 , THVD2410 Hello,
I am working on a cable interface for a military device. I plan to use RS485 on the communication lines to increase noise immunity and I've selected the THVD1400 to do the…
Part Number: THVD1400 Dear Expert ,
Good day!
Our customer want to use THVD1400 to make a 485 network system. There are more than 200 loads, and the transmission distance is about 28 meters. The load is evenly distributed. The resistance of the number…
Part Number: THVD1400 Hi team,
My customer wants to find solution to replace the MAX1544/MAX1543/MAX1344.
The key requirements:
support V.24/V.35/RS449/X.21/RS530
support DTE/DCE
support RS-232
Do we have some solutions to replace it?
Thanks.
Part Number: ISOW1412 Other Parts Discussed in Thread: THVD1400 , Dear Experts, I want to ask about protection of RS485 devices. We will have two RS485 communication, one for the internal bus among cards and second one for communnication with external world…
Hi Krzysztof,
This Echo behavior you're seeing is called out in the datasheet and is part of how the device works (see image below).
As Clemen's pointed out, this behavior is linked to the auto direction feature for the device.
The THVD1400 is…
Hello Park & Clemens,
We have stuided the ANs & have created following design decisions for our use case.Can you kindly review & share your valueable feedback on the attached schematic?
We have added Split termination with 0.5% tolerance resisitors…
1. We do not know if this actually is a problem. If the capacitance is too high, the signal edges are too slow (this would be visible in the scope capture).
2. You need a pull-up on RO if you MCU's RXD pin needs a valid signal even when the receiver is…
No, I can't see signals inside the product. This is a product installed at a customer. I can't open it.
In our case the bus is working at 10kbps fixed.
THVD1406 has been working for other customers without problems. Just in one case it did not…
Hi Salvatore,
I agree with Clemens, what is the state of /SHDN during all of channel states on the scope capture?
Also on the PSPICE /HSPICE question we do not have models for the THVD1406 or THVD1400. We do have an IBIS model available for the THVD1400…
Other Parts Discussed in Thread: THVD1400 , THVD1406 , THVD1426 Dear support team, I need a RS485 transceiver IC with auto-direction control. I have two principle questions in this context: Question 1) About low 9600 baud rate, auto-direction control and fail…
