Hi, I am working on a project that uses the 74LS688 chip. Unfortunately,
I can't find this chip or any information on it, anywhere in Rochester.
The schematics I am useing to wire it up also don't say anything about
the pin-outs of it. It is called an "8-bit comparitor" and looks like it
is used to compare two 8-bit numbers (brilliant deduction, huh? :-) Well,
to make this story short, I can easily get two 74LS85 chips (4-bit
magnitude comparitors), the only thing is, I need the pin-out of the
74LS688 so I can find out what the functions of the outputs are (low when
=, or high, etc...)  So can someone who knows the pinout and functioning
of the 74LS688 please e-mail it to me? It would be greatly appreciated.
Thanks!
