Part Number: SN65HVD22 Hello, I have an RS-485 chip that I'm not sure if it's conterfeit or not. I have attached a picture of the chip in question. Markings on the bottom are KA024 and KB721. I have attached a picture of one of the chips.
Thank you

Hi Sir,
The reference circuit is on page 25 in the SN65HVD22EVM User's Guide .
At the receiver output, what is the function of R21 in the circuit? How to calculate the R21 resistance value is 453 Ohm? Why is the R12 not…
Part Number: SN65HVD22 Other Parts Discussed in Thread: THVD2450 Hi Team,
Cable length and signaling rate of this product is up to1200m at 500 kbps (with slew rate limit) and node is Up to 256.
Dose it mean it can use with 1200m, 500kbps and 256…

great news you plan to use our SN65HVD22 in your project. I would like to let the product experts comment whether this is the best fit for your application, but I am sure you have made a good choice. Please share your results as…
Other Parts Discussed in Thread: SN65HVD22 , ISO15 Hi,
I'm looking for communication that can handle a network with ~250kbps for one 10km segment (very large scale network).
In your website, I found the SN65HVD22, Extended Common-Mode RS-485 Transceivers…
Part Number: THVD1424 Other Parts Discussed in Thread: SN65HVD22 Tool/software: Hi Team,
I have a question about SLLA628. https://www.ti.com/lit/an/slla628/slla628.pdf
There exists a tradeoff between speed and maximum bus length. If 5% jitter is acceptable…
Part Number: SN65HVD24 Other Parts Discussed in Thread: THVD1450 , SN65HVD22 Hi support team.
My customer uses the SN65HVD24 interconnected. Distinguish the two SN65HVD24s from the A side and the B side. In addition, there is an offset of about 0.6V…
Hi Brewster,
This is the PCN that issued that calls out the new design/die.

If you have the original sticker that the devices came in, you can 'CSO' for the device came from. Line 20L if it is RFB it is the new die…
SN65HVD22 would be able to handle these voltages and data rates. You could pull the DE (driver enable) pin low so that it behaves only as a receiver. The only issue is that it uses a 5-V supply voltage, and so the output voltage would be from 0-5 V. Is…
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.
