TTL： Transistor Transistor Logic，晶体管-晶体管逻辑电平。 比如：0V代表逻辑低电平，5V代表逻辑高电平。 像STM32单片机串口引脚输出的逻辑高电平就是3.3V。

Transistor–transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. It is called transistor–transistor logic because both the logic gating ...

Here we demonstrate that a significant reduction in the use of field-effect transistors can be achieved by constructing carbon nanotube-based integrated circuits based on a pass-transistor logic ...

TTL (transistor transistor logic) logic chips are pretty outdated today, but they do have all of the basics necessary for building a computer – logic gates, counters, buffers, and registers.

From Transistor-Transistor Logic (TTL) all the way to today’s DisplayPort digital display interface, here is an overview of panel display interfaces from the early 1960s to 2007 and a bird’s-eye view ...

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 ...

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 ...
