I saw a request about how to interface an audio signal with a microcontroller for logic level switching. I started thinking a lot about it and found some quick fixes. This post has my ramblings about ...

The archetypal logic gate family is of course the 74 series of TTL devices, of which there are many variants with ever-improving characteristics since the series first saw the light of day in the ...

Both devices can be used for logic translation between a GTL processor and a chipset, ASIC or motherboard using TTL logic, or for logic translation between a TTL processor and a GTL backplane.

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 ...

Model NT2140 discrete AC power input modules have joined the BusWorks NT2000 Ethernet remote I/O family, and can sense on/off AC voltage levels and contact closures to ...
