    [FAQ] How do I select a bypass capacitor for a CMOS logic device?

    For the short answer - use a 0.1uF for single supply logic devices like the SN74LVC1G08, or a 0.022uF capacitor for each supply pin of a device with multiple supply pins, such as the SN74LVC16244A (which has 4 supply pins). Why do we need a bypass capacitor...
