Part Number: SN65HVD75 Dears：
as above figure12&13，it is all TX direction， Figure 12 is easy to know，the timing is signal in to differential out ; however, in figure13, is it signal in to out port timing ?
what is the mean "driver enable and disable…
Part Number: SN65HVD75 Dear ：
I have one product with RS485 SN65HVD75DGKR to do withstand voltage test, but I found the leakage current is 11mA above， standard request is below 10mA，so I need you help to give me suggestion.
test condition： The A/B…
Part Number: SN65HVD75 Other Parts Discussed in Thread: SN65HVD72 , Hello,
Due to the shortage of SN65HVD72, I am considering to use SN65HVD75 as the substitute in a current board. From the data sheet, they are pin compatible but the signal rate…
Part Number: SN65HVD75 Do we have the 485 with lower power consumption? This application is on the water meter, the power supply is lithium battery, so the voltage needs to withstand about 5V.
If not, is the chip suitable for this application?Thanks…
Part Number: SN65HVD75 Hi Team,
For the receiver inputs, does it have push-pull output?
It's found that there is leakage path when R pin is pulled up to another 3.3V power supply if Vcc is powered off earlier than 3.3V, so I wondering there should…
Hello Hao, thanks for your reply!
i also think, that the second schematic is the better option. In an application report from TI i also found an comparison for the transceiver design. In this document the order is: transceiver, bias, series resistor…
Part Number: SN65HVD75 Other Parts Discussed in Thread: THVD1450 Hi,
My customer used to use SN65HVD75, now they are searching for a 5V device with the same small package size as SN65HVD75. SN65HVD75 can support a "VSON" package. please kindly suggest…
Part Number: SN65HVD75 Hi we have a major issue wth the SN65HVD75 parts. We have one main board and 32 output boards which each plug into the main board. We are running at 500kBaud.
In normal mode, the program runs well and there are no problems after…
Part Number: SN65HVD75 Hi,
Customer raised below 2 questions.
1. Should the PIN A and B trace route as differential signal trace? Any trace impedance requirement?
2. Is PIN R required trace impedance control?
Best regards,
Randy Chen
