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 ...
A variety of logic-circuit techniques have been in use since the 1960s, when integrated logic first came into existence. In the beginning was Resistor-Transistor Logic (RTL). Then came ...
This may very well be the smallest homemade TTL CPU we’ve ever seen. Measuring at one square inch, this tiny chip boasts 40 connections, an 8-bit databus, a 16-bit address bus, a 64 kB memory space, ...
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 ...
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 ...
