[sdiy] Intro and basic IC compatibility question

[phillip m gallo]

Tim,

No, the 74C14 and the 74HC14 are different technologies for the same
pinout.  Depending upon the use, you might be able to interchange them
but the 'HC14 is not a "rare" component.   You should be able to locally
source an 'HC14, even Radio Shack carries these now and again, also
check for a JIMPAK distributor.

regards,
p

Hi guys,
I've been following the threads here for a while, most is way over my
head 
but I find it quite interesting nonetheless.  I'm really enjoying my
first 
DIY project, the p9700s modular kit from Paia.  I can easily spend hours

working on it and I find even the dreaded flying wires to be enjoyable
in 
their own way.  I'll probably feel differently once the whole thing is 
complete but for now I'm having great fun.
The only glitch to date is a number of missing parts though to their
credit 
the Paia guys have been very quick to send replacements once I report
the 
omissions.  I am currently missing a Hex Inverter IC (74HC14) from the 
Midi-CV module that hasn't shown up yet.  My VCO will be completed
tonight, 
and I need the Midi-CV module to power and test it.  I want to buy the 
missing IC from a local shop but I'm worried about going that route
given my 
status as total SDIY noob.  My electronics store has the 'NTE
equivalent' 
which the salesboy thinks will work.  I really don't want to use the
wrong 
part and ruin all my hard work just because I'm impatient.

My question: is the NTE74C14 compatible with the 74HC14 that Paia should

have sent me?


Thanks very much!  Have a great weekend.

Tim
