ISO7820LL: Need your help to recommend, two-way transmission, with isolation, without EN PIN, can replace the ADN4650 LVDS;

Part Number: ISO7820LL

Need your help to recommend, two-way transmission, with isolation, without EN PIN, can replace the ADN4650 LVDS;
The search found that ISO7820LL seems to be more suitable, but our CPU does not enable the trigger signal, and the program does not define the enable port. The original design is an isolation transformer, so the trigger signal is not enabled. The EN PIN of the ISO7820LL requires a high and low power Level control；

Thanks

Hi Elsa,

Thank you for posting to E2E! Although the ISO782xLL has ENable pins, they do not need to be controlled by logic during device operation. ENable pins can be left floating or connected to their corresponding Vccx by a 4.7kOhm resistor to continuously enable outputs.

Is this acceptable for your system?

Please expect follow up responses during business hours.

Best,

Manuel Chavez
