ADM2484E Replace TI ISO3080

Dear All:

ADM2484E Pin7 & Pin 10 is NC pin ,TI  ISO3080 show GND1 & GND 2 ,But ADM2484E datasheet Pin7 & Pin 10 description "No Connect. This pin must be left floating." if mount ISO3080 PCB Layout have any  question ??

Best

    Hi Jack,

    I can confirm that pin 7 and pin 10 are more specifically than NC, actually NIC ("Not internally connected") so while not a footprint match they are compatible footprints.

    One significant point though is that ADM2484E requires 3.3V on Vdd2, while ISO3080 uses 5V on Vdd2. ADM2491E could be used instead even though it is a high speed part (it will work at low data rates too, just with faster edge transitions).

    Best regards,
