Part Number: SN65HVD21 Other Parts Discussed in Thread: SN65HVD77 , , THVD1550 , THVD1439V , THVD1439 , THVD1420 Hi Team, What is the minimum storage temperature for SN65HVD21D? Thanks in advance! Kind Regards, Jejomar
Other Parts Discussed in Thread: SN65HVD21 Interface team,
I have a customer exploring different options to maximize the # of nodes, length, and speed of a 485 line. Can you help to answer their questions below?
1) I’ve been looking at available…
Part Number: SN65HVD23 Other Parts Discussed in Thread: SN65HVD21 , SN65HVD24 , SN65HVD20 , RS485-HF-DPLX-EVM Hi,
Looking to use the SN65HVD23 in an application where continuous data is being sent unidirectionally through up to 200m of shielded twisted…
Part Number: SN65176B Other Parts Discussed in Thread: THVD2450 , SN65HVD21 Hi expert,
I have a customer used SN65176B. And they will measure some voltage spike on 485A/485B-GND, when the AC side air-switch turns on.
I know it already violate the…
Kirill,
As I understand, V.11/X.27 does no longer in use. The latest version is V.11 published in 1996, in which the electrical characteristics is similar to TIA/EIA-422-B. SN65HVD21 meets most of TIA/EIA-422-B. The only difference is Ios (bus short…
Yes, the die for this device was updated to be using 300mm wafer technology. It looks like the PCN also includes a top marking change.

Hi Cosmin,
It is generally possible to connect an RS-232 transceiver to the same connector pins as an RS-485 transceiver as long as you have the ability on each device to disable its respective driver output (so that multiple active drivers don't contend…
Thank you Casey McCrea. I apologize I wrote down the wrong part for some reason the part I am using to drive is the SN65HVD21 not the SN65MLVD. Which is the same part used in the module. However, I believe this has no effect on the impedance lines themselves…
Austria,
I don't recommend software switching the 120 ohm on board. The load is only used at the ends of the cable and the software doesn't know if the connection is at an end or not. The person who runs the cable should add 120 ohm externally at the…
