right, you have it reversed. They should blow out the moment
you turn
the power on. VCC is +power, VSS is ground.
Someone told me once that VCC means voltage for
collector-collector,
or many collectors, something you can sometimes see peeking
towards
+ power rail. VSS means source-source - negative supply. So
in CMOS
it should rather be VDD like drain-drain for positive
supply.
Assuming we talk about NPN or N-FET only.
