Part Number: SN65HVD78
Hi Expert,
Is it possible to combine D and R pin together for half-duplex RS-485 application as below configuration?
The left side of SN65HVD78 is FPGA HR Bank, it is Bi-direction pin.
Thanks.
Part Number: SN65HVD78 Other Parts Discussed in Thread: PROFIBUS , , INA185 Hello,
We use SN65HDV for a fieldbus like Profibus. We would like to know if an equipment is connected or not to the wire network when we send data. We don't know how to detect…
Part Number: SN65HVD78 Hello Support team,
My customer inquiries R pin. When they use it as receiver, does SN65HVD78D need pull up or pull down resister? R pin looks like to be push-pull output but Fig.26 uses 10k ohm pull up resister.
Thanks…
Part Number: SN65HVD78 Hello Sir.
We use the SN65HVD78 device, there is a state of abnormal operation. (As shown below)
SPI_CLK_A/B signal, the converted CLK will be one less (red circle), which will cause our data transmission error.
Please help…
Part Number: SN65HVD78 Hello,
Is possible to connect Thermal pad (VSON package) to GND? There is no description in datasheet. In PIN table TP is missing. Below the package drawing, note 3. Is only written that, we must solder the TP to PCB, for better…
Part Number: SN65HVD78 Hello Interface Experts,
Application is running in receiving mode only and transmitter is not used .
There is a graph 8 given for the “dynamic supply current consumption Versus signaling rate”.
Is it same for both transmitter…
