Other Parts Discussed in Thread: TIDA-00333 [ ISO3082 ] TIDA-00333 Circuit Schematics
Hi, I have recognized that the no power supply connected to U6 in the schematics of TIDA-00333. The power of SN74LVC2G14DBV is supplied from Vs1. Correct?
Thanks, Ken
HI Michael,
I apologize for the delay - I was out of the office for the last two weeks. I am sorry for any inconvenience this may have caused!
1. I would suggest 2 RS-485 repeaters (1 at 1km and 1 at 2km - as max is about 1.2km without repeater (at…
AAKASH,
Thank you. I see that you are using the exact same schematic as the TIDA-00333. That reference design advertises a max data rate of 100 kbps. Does your board still have the same issue at lower speeds?
Respectfully,
Lucas
Hi Abdel,
I see you are looking for an RS-485 bus isolator and not an isolated RS-485 transceiver. Unfortunately, we do not have a single chip solution that can isolate the bus independently.
The most common practice is to isolate the bus at a communication…
Part Number: ISO3082 Other Parts Discussed in Thread: TIDA-00333 ,
Hi,
In the TIDA-00333 reference design ( ttp://www.ti.com/lit/ug/tidu590/tidu590.pdf ) are jumpers ( JP1, JP2, JP3, JP4 ) to connect the bias resistors. In which case i should use these resistor…
Part Number: DS89C21 Other Parts Discussed in Thread: TIDA-00333 , THVD1510 Hi all,
I am designing an RS422 point-to-point link ring network (connecting STM32 uControllers) with DS89C21 Transceivers. The distance between the 2 nodes will be 2 km and I…
Hy Michael,
my repeater circuit comes from this:
www.ti.com/.../tida-00333 ;tisearch=Search-EN-Everything
but i have changed some component.
My purpose is to transmit RS485 data at 500k or 250k speed at distance of 500m or more.
Now i can if i do not…

i need to build a DMX RDM SPLITTER with ISO 3082
this SPLITTER must be completly integreted on a DMX RDM 4 ch board
this board use an ISO 3082 and run…
Hi Craig,
This topic comes up from time to time and you are on the right track with your thinking. Several years ago one of our great systems and applications engineers, Thomas Kugelstadt, wrote a great app note on the topic. The application report can…
