Part Number: SN65HVD1785 Other Parts Discussed in Thread: AM26C31 , , THVD2410V , THVD2410 Hi everybody,
I'm recreating my TTL to RS-422 signal splitter. The first one was created using AM26C31 and works fine. I wanted to make my design more robust, so…
Part Number: SN65HVD1785 Hello, We have received some parts from the gray market, and we have a doubt if these parts are genuine parts.
The left one comes from previous order by authorised dealer.
Can you help us?
If you don't mind, can you share which devices were connected? SN65HVD1785 has high bus fault voltage, which can sustain high DC. I suspect the issue might come from unexpected ESD events. But since it's A pin always gets damaged, is it possible to…
Part Number: SN65HVD1785 Hi team
I am trying to test performance against negative voltage on the B pin, but it doesn't work.
In the following layout, -30V is applied to B pin in a pseudo manner by applying 30V to GND. However, this method broke the…

I have been using SN65HVD485 on my slave boards, on my new board I need to change to SN65HVD1785 . The master is an ILX34_MBS485 from Prosoft, running at 19200 .I have 20 slaves on the bus and I am getting some SN65HVD485 failures…
Part Number: SN65HVD1785 We have developed a system that employs the SN65HVD1785 to interface between several modules. Our modules are powered from a 24VDC source. The 24VDC source can be common(shared) or independently supplied to the modules. Where the…
Macit,
That sounds like a good plan to me. If there were any issues with the TVS connection previously it would explain why the system is failing ESD testing. Testing on the new PCB should help confirm. Please let me know what you find - I'm eager…
Hello,
I still have no resolution for this problem.
I need to replace SN65HVD485E with a device that is capable of surviving over voltage faults of up to 50V,
The SN65HVD485E are failing in the field with short circuits between A or B and Gnd.
I tried…
Part Number: SN65HVD1785 Other Parts Discussed in Thread: SN65LBC184 Hi Expert.
My customer request for RS-485 products which have both "Bus fault protection : ±60V" and "Surge current : 6A" .
Does SN65HVD1785 or other products…
