Part Number: SN65HVD20 Other Parts Discussed in Thread: THVD1429 Dear:
Could you help me promote a RS-485 chip,request parameter:aound the cable length 500m,the data rate can meet 1Mbps above, and with surge protection
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…
Other Parts Discussed in Thread: THVD1450 , THVD1429 Hello team,
Do we have similar device to ISL3298EFRTZ-T(RS-485/RS-422 Transmitters)?
I searched it on TI.com, but I think we do not have same configuration device. My customer is searching it.
If you…

Hi,
Back to this post for THVD1550 for practical reasons, customer is unable to reduce the stub below about 18 cm. Value much greater than the 1.9 cm that this…
Danilo,
The most recently released 10M-50Mbps RS-485 transceivers are: THVD1550, THVD1450, THVD1520, THVD1450, and THVD1429. BTW, this e2e post has detailed information about more new devices.
You're correct about the failsafe feature of TI devices -…
Hi Nobuo,
Q.1) According to datasheet of AM26C31 , typ value of VOH =3.4V with VCC=5V supplied, so I suppose voltage across termination voltage would be 3.4V. Is it OK to think 3.4^2/120 = 0.096W, or should we recommend 5^2/120 = 0.21W in case of BUS fault…
Hi Max,
Thanks for your 1rst reply.
I need 2 transmit chnnels and two receive channels. Concerning Baud rate : 115K is enough.
So wich part do you recommand ? Emc immunity can be an important criteria & small package too.
I already choose the rs485…
Dear Max,
Thank you for reply.
"THVD1450 and THVD1429", Is that compatible to SN65HVD08 ?
On your reply, 'RS-485 pull-up resistor on the "R" output' is like to U3.1 on my circuits, Is it right?
And, 'quickly discharging fast…
Part Number: SN65HVD3082E Other Parts Discussed in Thread: THVD1500 , , THVD1550 , THVD2450 , THVD1429 , THVD1450 Hi all,
I have to design a new interface board for RS485 half duplex communication over a long distance (up to 100 m) and this will be produced…
Part Number: ISO1500 Other Parts Discussed in Thread: THVD1429 Hi, Community member
I want to have the same surge protection function as THVD1429 in ISO1500.
(±2.5kV IEC61000-4-5)
Please tell us your recommended TVS.
Waiting for your answer…
