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

GaN laser driver has LVDS logic inputs EPC has announced a laser driver that integrates a 40V 10A GaN power switch with a differential input gate driver. Called EPC21603, its inputs are LVDS ...

However, it requires a “translator” to make things smooth and secure. So, let me try to share one idea for building an “Audio to TTL” adapter to convert the audio signal input into a logic high/low ...

This debugging process is complicated by the fact that these aren’t your basic 5V TTL-style logic cards, but rather use -12- and 0V-based high-threshold logic (HTL).

TTL logic inputs were not supposed to be connected to a power rail directly—you’re supposed to pull it up with a resistor to limit any input current.

What do you think I found? The power pin on the device was unconnected! When did that mean? After thinking a bit about what I learned in my TTL logic design class I figured it out. When at least one ...

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 ...
