Part Number: THVD1449 Tool/software: Hi,
Is the RFS pull up or pull down needed on A and B pins of THVD1449DR keeping in view the full speed grade and the full length it supports?
Part Number: THVD1449 Other Parts Discussed in Thread: ISO3088 , ISOW1432 Tool/software: Hi
I am working on the following RS485 transceiver.
Can you suggest any transformer coupling or any other isolation method to provide galvanic isolation to the bus…
Part Number: THVD1449 Tool/software: Hello,
in the TI application note " Simplifying Surge Protection for RS-485 Using Integrated Designs " by Parker Dodson it is shown in a block diagram (fig 3-1) that the TVS diodes are integrated in the housing…
Part Number: THVD1449 Other Parts Discussed in Thread: SN65176B Hi team,
I have a customer is testing THVD1449 and have a question.
When Reciever side is Enable and Driver is 0V, the tPZH and tPZL will be 4us and 10us. And they find out that SN65176B is…
Part Number: THVD1449 Hi team,
Does it have the specific test-mode or -operation, which is out of normal operation, just for final-test or others, and not mentioned in datasheet?
If yes, how does this specific operation mode happen and how to avoid it…
Part Number: THVD1439 Other Parts Discussed in Thread: THVD1449 , Hello, is this device robust enough to be used without external TVS diodes protection? If not can you recommend an alternate device
thanks
Hi Michael,
1. So the THVD1420, THVD1450, and THVD1449 are all decent options in this application:
1a) The THVD1450 offers the highest IEC ESD protection (+/-18kV), but additional external protection may be required.
1b) The THVD1420 offers high IEC…
Hi Luis,
So based on the schematic - I definitely think moving towards a surge protected device is possible - UART signals work well with RS-485 so the slight change in interface (RS-422 to RS-485) probably isn't much of an issue.
At 3.3V we have…
The AM26LV31E is the only quad-channel device with these characteristics.
The only possible replacements are one-channels transceivers like the SN65HVD75 or THVD1449.
