When you go on your favorite cheap online shopping platform and order a batch of 74LS logic ICs, what do you get? Most likely relabeled 74HC ICs, if the results of an AliExpress order by [More Fun ...
Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...
In this column, we consider the evolution of complementary metal-oxide semiconductor (CMOS) technology, which was invented by Frank Wanlass in 1963. In this column, we consider the evolution of ...
The three main logic families in the 1980s were TTL, ECL, and CMOS. The three main logic families in the 1980s were TTL, ECL, and CMOS. In my previous column, we started our look at logic data sheets ...
TTL is the VLSI logic family that preceded CMOS, more or less (there are several others, and I'm fairly fuzzy on the detailed history, so hopefully this will be more or less accurate).<BR><BR>I doubt ...
