Simple Logic Gates using Diodes


Diodes can be used for implementing simple logic gates such as AND or OR combinations. For the AND gate, all inputs must be tied to high, 5V for the output logic high. For OR gate, the output is high if any input(s) are high.

Hot-Swap Circuits with Inrush Current Limiter

  To provide continuous current sensing and limiting, this hot-swap circuit uses a PNP transistor and a current sense resistor of 0.333R. Wh...
