Hello Manu,
The pull-up/pull-down resistors are not necessary for the THVD1500. This device already has it integrated internally.
For your attached image, the SN65HVD888 devices have auto polarity detection which requires the pull-up/pull-down resistors…
Part Number: THVD1505 Other Parts Discussed in Thread: THVD1500 The THVD1505 (Automatic Bus-Polarity Correcting) and THVD1500 half-duplex RS-485 transceiver were designed to meet the requirements of part 11 Serial Communication Protocol RS-485 standard in the…

Hi ,
I'm planning to use the below circuit for optically isolated RS-485 interface. Can anyone confirm if the below design is valid? My primary concern is receiver pin of XCVR where the IOL limit is 8mA. Whereas I have…
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 a molex…

THVD1505: SGCC (State Grid Corporation of China) certified RS-485 transceivers
The internal protection is able to handle ESD strikes because those are extremely short and contain very little energy. A surge of 120 µs, even at a relatively low voltage, is likely to burn out the internal ESD diodes.
If you cannot stay inside…
