Hi everyone,
I'm checking a design, that it's basically this evaluation board with some adds to add RS-485 Half-Duplex and RS-485 Full-Duplex and RS-422 support: …
Part Number: SN65HVD1473
Hi everyone,
I'm designing a shield board for the Raspberry Pi 3B with the possibility of using RS-485 or RS-422 (With some jumpers) and using a configuration similar to this scheme for activating the transmission pins with…

Part Number: ISO1450 Other Parts Discussed in Thread: ISOW7841 , THVD1450 , SN65HVD1473 Dear Mr./Ms,
I am using ISO1450 to isolate RS485 interfaces. But in my design, i don't supply VCC2 and using VCC1=3,3V.
Can you tell me that right?
Thanks and Best…
Hi Lilian,
Thanks for posting your question on E2E. We do not currently have an isolated RS-485 transceiver that supports 3kVrms Isolation. You are correct that the ISO35 datasheet specification for isolation is 2500 Vrms as per UL 1577 and CSA CA5A and…
Hi,
Yes, your calculations are correct. ISOW7841 can provide 74mA of output current and SN65HVD72 would require 62mA at 0.25MHz.
This combination solution should not face any problems.
Iiso(out) shows the output current available at the VISO pin of…
