Other Parts Discussed in Thread: ISO7341C, ISO7241C,
The digital Isolator originally used by the customer's product is ISO7241CDW, and there is no problem. The isolated interface is RS-485 transceiver, the maximum communication rate is 57kbps, and the load is PLC. When using ISO7341FCDW for alternative test, it is found that there is a packet loss rate of 3%.
The test environment is the same. A total of 10 boards have been tested, all of which are pin to pin to replace ISO7241CDW. The test results are about 3% packet loss rate.
Can ISO7241CDW be replaced by ISO7341FCDW ? If not, why
