TI TTL Data Book for Design Engineers, 1st edition was copyrighted 1973.
It lists the 74154 and other parts up to the 74298.
How come the neat CMOS chips like BCD adders and stuff have never made it
to TTL?
Does
anyone remember a construction project from Popular Electronics (I
think), perhaps in the late '60's, that made a simple processor from a
74154 4 line demultiplexer and a handful of diodes?
Did they even have 74154's in the late 1960s? At any rate, sounds
like an
interesting project.
