PRODUCTION DATA
When using a low value ceramic bypass capacitor, the capacitor must be located as close to the VCC pin of the device as possible. This eliminates as much trace inductance effects as possible and gives the internal device rail a cleaner voltage supply. Using surface mount capacitors also reduces lead length and lessens the chance of noise coupling into the effective antenna created by through-hole components.
