I'm using a level shifter to go from 3.3V to 5V (digital/analog). According to the datasheet, if I put 1 ground on the left side of the IC and the other on the right, it would tie the grounds together inside the IC.
This would be bad since I'm trying to use a single point star ground with separate ground planes and it seems like this ruins it. If I want to keep using the same part, whats the best approach? I'm thinking tie both sides of the level shifter to the input ground and have the output current take a long path through the single point ground? or vice versa?
