目前应用最广泛的数字电路是TTL电路和CMOS电路。 TTL电路以双极型晶体管（三极管）为开关元件，所以又称双极型集成电路。双极型数字集成电路是利用电子和空穴两种不同极性的载流子进行电传导的器件。 它具有速度高（开关速度快）、驱动能力强等优点，但 ...

Transistor-transistor-logic or TTL parts have been around for a long time and now and then, I still seem to run across this or that “thing” where they've been designed in, not necessarily in the ...

Since you can now get CMOS parts with comparable speeds to these TTL parts, why would anyone continue to use TTL? In fact, there a few reasons… Since you can now get CMOS parts with comparable speeds ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Only eight lithography masks to create a low-power custom logic chips, compared with 20+ for CMOS, is the claim of Nottingham-based fabless chip start-up ‘Search For The Next’ (SFN). As such, ...

[Donn] wanted know exactly what is going on inside of a processor so naturally he built a CPU out of TTL components. He had previously built a couple of versions of a computer based on the Z80 ...

The panel industry is rapidly accelerating to higher resolution and a greater number of bits per colour. Breakthroughs in resolution and color are possible only when increasing the overall data rate ...
