- You might add: so long as you are handling modern 4xxxB ic's. If you
- get hold of some old pieces with no suffix you will find that they
- are the source of CMOS's delicate reputation. BTW, I worked briefly
- at a company best left unnamed where some of the techs routinely swapped
- CMOS chips in live circuits. They seemed to get by with this, at least
- in the short term. I've always thought that a junction could be damaged
- without failing immediately so this seemed foolish to me.
