ISO7710-Q1: Please help me choose the correct package of ISO7710-Q1

Hello,

Thank you for your question.

The ISO7710-Q1 is avialable in 2 different package sizes: DW (SOIC 16-pin) package and D (SOIC 8-pin) package.

The DW package is 10.30 mm × 7.50 mm and is the larger package size of the two options. If you would like the IC taking up less board space, the D package will be a good option as it is 4.90 mm × 3.91 mm.

For this device, both package sizes have the same isolation ratings. Please check the ISO7710-Q1 datasheet for more information: ISO7710-Q1 High Speed, Robust EMC Reinforced Single-Channel Digital Isolator datasheet (Rev. B) (ti.com)
