Hello all,
Suppose I have, for example, a SSOP-24 IC with Vcc on pin 1 and ground on pin 13(IE far from each other). If I want to place one bypass cap across Vcc and ground near this IC I should try to place the IC as close to the Vcc and ground pins as possible but in this case the pins are far from each other.
Let's assume I have a ground plane and Vcc plane under this IC. What I'm wondering is in this case what is the preferred approach. Does it matter whether the cap is next to the Vcc pin or next to the ground pin? My first thought is that it shouldn't matter because the loop area should be(mostly) the same in both cases. But maybe I'm not thinking of something.
Thanks for your input!
