Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: THVD1400
Tool/software:
Hello E2E Community,
We are trying to improve the Surge & Transient immunity of our sensor nodes that are interfaced using THVD1400.
We have a TVS diode with following specifications - based on your expert knowledge…
Part Number: THVD1400 Tool/software: Hi All,
I have a question about the THVD1400. The maximum rated voltages of inputs A and B are as follows, so I understand that it is input tolerant. Is my understanding correct?
Best Regards, Ishiwata
Part Number: THVD1400 Other Parts Discussed in Thread: SN65HVD75 Tool/software: HI,
The customer uses THVD1400 as the RS485 transceiver. Feedback power consumption is high and cannot meet the demand. Is there a recommended product with better power consumption…
Part Number: THVD1400 Tool/software: Hi
I am using this THVD chip and I am trying to reduce current on my design.
currently I have 1mA current flowing through R44. even when there is no power on the RS485.
I was trying some solution in order to reduce…
Part Number: THVD1400 Tool/software: Hi,
I am using THVD1400 for RS485 communication between my device.
I have the following schematics -
5VDC+RS485.pdf
I have a current issue when I start communicating with the device.
the datasheet mention about 1mA…
RS-485 transceivers are designed to handle ground shifts (±7 V for the THVD1400). Such ground shifts can happen in industrial applications, but in your case, where all nodes share the same power supply, they would not be a problem. So you can indeed use…
Part Number: THVD1400 hi，
The customer uses THVD1400DR as the RS485 transceiver, the sending end is powered by 3.3V, the receiving end uses 5V power supply and point-to-point communication. Does it affect the transmission distance？
In order to reduce…
Part Number: THVD1400 Hello, I'm working on RS485 , currently using THVD1400DR but getting issues with A and B dropping voltage, so I decided to make some simulation. It turned out that the THVD1400DR that I'm using only provides the .ibis model and…
Part Number: THVD1400 Unlike datasheets for other devices that clearly show biasing resistors or say that they are not required, this one only mentions "Internal biasing of the receiver inputs" once. Planning on using these at 460800 baud with…
Tarun,
Please go here: https://www.ti.com/support-quality/additional-information/customer-returns.html for a return - as at this moment this is starting to look possibly like a quality issue with the device.
At this point there doesn't seem to be an application…
