Part Number: THVD1520 Other Parts Discussed in Thread: SN65176B Tool/software: Hi Team,
My customer has a problem of the received data from salve. There are 6 slaves in the system and the data from last one (the most far from the master) is abnormal…
Part Number: THVD1520 Dears, We promote THVD1520DR to replace the ST485ABDR,When they test the fuction find data lost issue. The Master is 1PCS,the Slave is 16 PCS and the Peripheral circuit is the same as ST485ABDR.
Pls kindly help to check the schematic…
Part Number: THVD1520 Hi team,
Can you help review the schematic of THVD1520?
Also, I am not sure that whether the existence of R16 and R21 will influence the normal work. Seems that no pull-up/down resistors are utilized in reference design. Thanks…
Part Number: THVD1520 Hi Team,
we are using THVD1520 for RS485 communication, the configuration is two twisted pair cable for full duplex RS485, distance is 1000 meters and baudrate is 115.2Kbps. we need make equivalent circuit to simulate the 1000…
Part Number: THVD1520 When designing a RS485 in the system, is there power sequence requirement?
What if the MCU's signal sends to Drive pin of RS485 device before its VCC is powered? We'd like to know if there is a concern on the power sequence.

Does TI has TVS solution like below typ schematic? CDSOT23-SM712
Thanks!
Part Number: THVD1520 Hi Team
My customer is using THVD1500DR and encountering a shortage issue. We are considering transferring to THVD1520DR for replacement.
However, the data rate of THVD1520DR is much higher than THVD1500DR and I suppose the receiver…
Part Number: THVD1520 Other Parts Discussed in Thread: THVD1505 , STRIKE Hi,
I was wondering if there were any design guides, pcb examples or references for the best method to protect an RS485 chip from ESD, surge and reverse polarity. We are using…
