The familiar five volts standard from back in the TTL days always struck me as odd. Back when I was just a poor kid trying to ...

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 ...

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 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 ...

The MSE 1000 modular multiplexer from HEIDENHAIN now features transistor–transistor logic (TTL) and inductive and analog interface modules. This allows for the connection of up to 250 devices and the ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

The device shown in Figure 17-1 is an RS-232–to–TTL converter board, designed to allow a PC with a serial (RS-232) port to communicate with a device that has a console (TTL) port. External converters ...
