ISO1176T: Isolated RS485

Part Number: ISO1176T
Other Parts Discussed in Thread: ISO1410, SN6501, SN6507

Hi,

Good Day.

I am designing Isolated RS485 circuit for 8 sensors. Following are the requirements

1) Output voltage for RS485 transceiver (isolated side) and for sensor loads: 5V

2) Output current for RS485 transceiver (isolated side) and for sensor loads: 150mA + 100mA for eight sensors

3) Output power switching control

4) Data rate for half-duplex, isolated RS485 transceiver: 19.2kbaud

5) Logic IO voltage (CPU side of RS485 transceiver) is all 3.3V LVTTL

6) Consider EMI / ESD

7) Consider switchable termination (desired but not must)

8) Input voltage range:  Either 4.6VDC or 6.5VDC

9) Consider pin reversal capability for RS485 transceiver (A/B) pins (desired but not must)

Could you please suggest integrated solutions such as ISO1176T or other solutions such as ISO1410 with external isolated DC-DC converter ?

Please advise. Thank you very much.

Best Regards,

Ray Vincent
