You're in luck.  Both chips are identical.  You see, the generic number of the
chip is 565.  But manufacturers like to add their own prefixes and suffixes.
Signetics starts a lot of their linear part numbers with NE or SE, depending
on whether the part is usable over the commercial or military temperature
ranges, respectively.  Signetics also attaches a suffix: N = plastic DIP, F =
ceramic DIP, D = surface mount, etc.  The LM565CN number is from National
Semiconductor.  The LM means 'linear monolithic.'  Other prefixes are: LF =
linear FET, LH = linear hybrid, ADC = A/D converter, etc.  The suffix C means
commercial temperature range; no C means military range.  N means plastic DIP,
H means metal can, etc.

So, both the NE565N and the LM565CN are the same chip, made by different
manufacturers.
