Static charges and CMOS
Storage methods need to be chosen to suit the product you wish to store.
If the IC was supplied in conductive foam (usually black, spongelike) or aluminium foil then the supplier thought it worth the hassle.
All 4000 series ICs should be protected from static discharges, some others also are sensitive to static, the datasheet should say.
LCD modules, some operational amps and most microprocessor chips require protection.
7400 series (if you ever use them) all generally have a low enough impedance to simply 'short out' the static discharge with no damage, though some types such as 74AC00 and 74HC00 still require protection.
The easy answer is to leave everything in the original packaging as long as possible and handle everything as little as possible.
DONT just sling things in a plastic bag - static damage is permanent and unpredictable; it may not show straight away - your latest project could work for ages with the damage then fail for no aparrent reason!
