Part Number: SN65HVD12 Other Parts Discussed in Thread: THVD1406 Tool/software: Dear Expert
There is a phenomenon of error code failure in our communication here.
Test signal quality and rise/fall slope. The signal quality from U3 front to isolated…
Part Number: SN65HVD12 Hello,
I found some SN65HVD12 not properly working that have the frame completely different from a working one: on the left the not working item.
On the top of the case there is the indicator notch for pin #1, which is…
Other Parts Discussed in Thread: SN65HVD12 Dear All,
I have connected RS485 IC (SN65HVD12) to LPC2387FBD100K microcontroller the attached is image for the references,
The Communication is by using UART.
I am facing the problem of the Multi slave…
Part Number: SN65HVD12 Other Parts Discussed in Thread: THVD1406 All,
Is it possible to hardwire the SN65HVD12 for Rx and Tx to always be active (DE = 1, RE_N = 0)? The FPGA does not have a spare pin to control remotely. Thanks!

Part Number: SN65HVD12 HI we bought from a distributor this part number SN65HVD12D dc2217 below picture in RED. But we check against our Master sample dc1710 above picture in Green., the X-Ray bondings are different as pictures above, I am not sure if…
Part Number: SN65HVD12 Dear Support,
Please help to check and confirm if the difference in the x-ray results are valid.
They have difference in lead frame. Please refer to photo for reference. Thanks
Part Number: SN65HVD12 Sir,
We used SN65HVD12DR in master and slave devices. At page 18 of the datasheet, it says 'Internal biasing of the receiver inputs causes the output to go failsafe-high when the transceiver is disconnected from the bus (open…
Part Number: SN65HVD12 Hello,
I would like to ask some questions below,
1. What's the value recommended to the three resistors between the PIN6 & PIN7 ?
2. What's the maximum current of the PIN6 & PIN7 (the driver output or receiver input)?
Thanks…
Part Number: SN65HVD12 Please find the problem description as enclosure. and please offer the comments. Very thanks.
