Part Number: SN65HVD20 Other Parts Discussed in Thread: SN65HVD23 , SN65ALS1176 , SN65HVD75 We are short of SN65HVD20 and we were looking for alternates but couldn't find one. Can you recommend a cross part or a drop-in replacement for SN65HVD20? Please…
Part Number: SN65HVD20 Other Parts Discussed in Thread: SN65HVD23 Since this part is out of stock, we are current looking for alternates but couldn't find any. Can you recommend a cross part or drop-in replacement for this? This issue is critical. Thank…
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
Part Number: SN65HVD20 Other Parts Discussed in Thread: STRIKE My customer requires IEC 61000-4-2 ratings for this device whereas the data sheet gives them with respect to JESD22. Is there a correlation? How can we get them the information they require…
Other Parts Discussed in Thread: SN65HVD20 My question concerns the SN65HVD20 RS485 transceiver. Please assume that I have a total of 32 nodes on my RS485 link. On the RS485 line side, how will the SN65HVD20 influence the RS485 link if one of the SN65HVD20…
Hi g.f.,
The two-wire connections can work as long as the ground potential differences do not cause the voltages seen by each transceiver (with respect to its own local ground) to exceed the common-mode operation voltage range of the device. For the …
Hi Roberto,
I'm also designing a USB to RS232/RS485/RS422 device, there I've used SN65HVD20 for RS485. For Receive Enable and Driver Enable I've used some logics with DTR and GPIO.
RE = P3.3 P3.1 + (NOT (P3.1)) (NOT(P3.3 DTR))
DE = ((NOT (DTR…

i'm new in this Forum. I have a master slave application with normal rs485 devices. It works on a noise environtment and some time the master microcontroller…
Julio,
the SN65HVD20 was tested in a point-to-point communication link for common-mode failures over a common-mode voltage range from -20V to +25V and over a frequency range from DC to 100 kHz. Across the entire range the SN65HVD20 performed failure free…
