Part Number: SN65HVD72 According to a previous discussion, Tyler Townsend answered " It looks like these two waveforms show two different devices / drivers. The SN65HVD7x RS-485 transceivers do not have a built in offset as shown in the second scope…
Part Number: SN65HVD72 Due to the recent shortage of semiconductors, we purchased a quantity of sn65hvd72 parts offshore, and when used in conjunction of earlier production parts, we see an offset of the data (see pictures).
Although the data decodes correctly…
Nihan,
I was suggesting that you remove the termination to get larger amplitude. As the termination are removed, you may also add pull up resistors on the A line and pull down resistors on the B line to further increase signal strength.

Hi guys.
I would like to use SN65HVD72 on my electronic product for the RS-485 communication.
Here I attach the part of the datasheet where you can fin the Electrical characterstics about SN65HVD72.
The Electrical characteristics…

We use the SN65HVD72DR product for RS485 communication in our products. But there is currently a stock problem. For this reason…
Part Number: SN65HVD72 Hi Team,
The Signaling rate of SN65HVD72D is "Up to 250 kbps" but there is no minimum value. Can it operate at 19.2kbps?

Part Number: SN65HVD72 Hi Team,
I use SN65HVD72 on one RS485 bus.
On one side of the bus (on the device)
when changing the nRE pin (from HIGHT to LOW and from LOW to HIGHT),
the Rx pin changes (LOW: duration 500ns)
It should be in a HIGHT state!
What…
Part Number: SN65HVD72 Dear all, we have got a design with SN65HVD72 and extra external world protection (similar to what is suggested in UG with 10R series resistors). Unfortunately, due to miswiring the device, in some cases the bus signals (A or B…
Part Number: SN65HVD72 Other Parts Discussed in Thread: THVD1439 , Hello Guys,
Good day.
Our customer have used SN65HVD72D in the past but cant find any to buy. Do you know if they can use THVD1439 in the same socket with the surge devices left off the…
Part Number: SN65HVD75 Other Parts Discussed in Thread: SN65HVD72 , Hello,
Due to the shortage of SN65HVD72, I am considering to use SN65HVD75 as the substitute in a current board. From the data sheet, they are pin compatible but the signal rate of the…
