Hi all, Hope you have nice weather too ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I need to improve the layout of a PCB for transient immunity. Most of my inputs to my 16F887 comprise of a transzorb to 0v, 330R in series with the input, a 0.1 uf to 0v, and a 4K7 pullup. My intention was to put the transzorb as close to the connector as poss, the 0.1uF as close to the PIC as poss, the pullup next to it, and the 330Rseries resistor between them.
Is this the best way?? (Approx 4cm between connector and PIC
Thank you for any advice
Jim
