Part Number: THVD1552 Hello,
We are thinking of using this transceiver that will have it's R output muxed with other serial driver via some diodes.
We need to ensure that when the bus cable is not connected the R pin is driven High for proper functioning…
Part Number: THVD1552 I am trying to build a board with general purpose RS 485 connectivity. I want to give the user the option of selecting a full duplex or half duplex network. By simply connecting DE to RE, A to Y, and B to Z, Can a full duplex transceiver…
Hi Zach,
The resistor selection is a trade-off between the amplitude of the differential offset introduced (larger tends to improve noise immunity) and the effective impedance of the termination (lower tends to decrease the number of nodes that can…
Hi Lanjie,
Which parameter would you like to see for THVD1552? Or do you mean the application curves like Figure 30?
Do you mean the maximum receiver output current is 24mA? This shows the maximum driving capability of the receiver. It depends on…
Part Number: THVD1552 HI, Staff
Relationship between the increase of nodes and data rate
In the THVD1552 data sheet, NODES is described as 196.
Q1:If you connect 256 (NODES) to THVD1552, what is the SIGNALING RATE? Q2:Can not support 256nodes, will…

Part Number: THVD1552 Other Parts Discussed in Thread: SN65HVD24 Hi Team,
My customer is using MAXIM MAX3292, and THVD1552 is newest 485 devices, but I checked that THVD1552 don't have PEE/PSET pin, I'm wondering if you have more suitable devices? thanks…
Part Number: THVD1552
Hi All
My customer is considering to use THVD1552 (Full-Duplex RS485). Their question is why THVD1552 recommends double termination resistor?
【THVD1552 Typical Application in datasheet】
Competitor device recommends termination…
