74ls14 instead of 74hc14 for data cable? Plz help!

[Mike]

I'm not too good with electronic components. That is I don't
understand much about them, but I can follow instructions well and I
got excellent soldering skills . I'm trying to make a data cable
for my cell phone but I have a slight problem that only you guys can
help me with. The schematic calls for a 74hc14 IC, but all I can get
my hands on locally is a 74ls14. I am unsure of the difference, so
could someone tell me if they work the same and if there are any
differences. Thanks.

Yes, there are differences. The 'LS' parts are TTL and have different
signal levels and power limits than the CMOS (HC, in this case)
cousins. That said, it still might work (or need slight
modifications). If you post a schematic perhaps we could tell if it
would work.
