Part Number: SN65HVD82 Hi, I have a design in which I parallel 8 SN65HVD82 RS485 channels as a multiplexer. All ~RE (receive enable) and DE (drive enable) lines are shorted together, and all driven at the same time from a single signal for half-duplex operation…
Part Number: SN65HVD82 hi，
During the operation of SN65HVD82, the dynamic current sending data causes voltage adjustment fluctuations in the isolation power supply, with peak to peak values around 200mV. Will this situation affect communication? What is…
Part Number: SN65HVD82 Other Parts Discussed in Thread: THVD1500 , THVD1510 Hi team,
Could you please help check if we have new device with better cost and P2P for 5V RS485 to replace SN65HVD82?
Thanks,
Brian
Part Number: SN65HVD82 Other Parts Discussed in Thread: THVD1400 , SN65HVD72 Hi team,
I have a wrong power rail design of the part SN65HVD82, and the Vsupply is 3.3V and out of the EC table supply voltage range and it could normally work.
And there is…
Part Number: SN65HVD82 Other Parts Discussed in Thread: ISO7721 Dear experts,
My customer using RS485 SN65HVD82 to transfer data. When the transceiver working from receiver to driver, the R pin drop abnormally for 1us and this causes the MCU mistake…
Part Number: SN65HVD82 Other Parts Discussed in Thread: THVD1510 , SN65HVD888 Team,
Could HVD888 be used instead of HVD82? Are they P2P dropped-in replacement? SN65HVD888 vs SN65HVD82 If not is there a way to make a PCB change to accommodate the use of…
Part Number: SN65HVD82 I want to monitor load capacity, the mean is that RS-485 BUS has more node（SN65HVD82）, I saw the requirement that input resistance is12K per load, i want to know the input resistance is between line and ground , or between line…
Part Number: SN65HVD82 Other Parts Discussed in Thread: THVD1410 , SN74LVC1G34 Hi Team, I've some doubts about designing a circuit using SN65HVD82. In the datasheet, it is clearly mentioned that the VCC is 4.5V to 5.5V. Do I need a level shifter at its…
