Original question:

ISO6740: DW0016B package

ISO3088: DW0016B Footprint selection

Part Number: ISO3088

Hi,

              I have a design where I have been using the IC ISO3088DWR. Datasheets shows two footprints for DW package. What is the difference between them and which one should I prefer.(Note: I don't have any HV system on the other end and my usage is for isolation purpose.)

    Hello Balakrishna, 

    Thank you for reaching out. The landing pattern on the left was introduced to comply with systems that have a >8mm clearance requirement (where clearance is the "line of sight" distance or the shortest air path between two conductors). 

    If 8mm clearance is not a requirement for your system and you have no HV concerns, then either land pattern will work.  

    Best,
    Andrew
