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.

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

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 ...

Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can be designed in many different ways. In this particular design, a combination of discrete and TTL logic ...

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 ...
