As I mentioned in my recent columns on the topic of adding pull-up or pull-down resistors to the inputs of unused or partially used logic gates and functions (see Part 1, Part 2, and Part 3), I was ...

A few months ago, a tweet by [Ken Shirriff] asking about simple digital simulators caught my attention. The topic came up again in May when a repair video by [CuriousMarc] featured one such simulat… ...

As electronic devices become more advanced, integrating complex logic into a single component becomes essential. Enter AND6, ...

The diagram below shows a complex logic gate combining three simple gates. It is possible to work out intermediate outputs (D, the output of the NOT gate, and E, the output of the AND gate) along ...
