Logic probes are great for debugging 7400 series logic chips and digital circuits. In this video, James makes a counter circuit and debugs each stage as he builds, with a Logic Probe. If you are wondering, “do I need a logic probe” this video shows how one can be used and even answers when you should consider buying one.

These days it is pretty rare to see a press release from a semiconductor company touting 5V TTL capabilities.  Diodes is upgrading their 5V TTL logic as reported by Electronics Weekly.  While the 5V operating will easily appeal to hobbyist, the package sizes may not.  They are not through-hole components.  However, the 74ACHT series will provide you surface mount solutions for AND, NAND, OR, NOR, XOR, Inverter, and Schmitt trigger glue logic. Diodes can be found…
