Power Supply Issues

Logic ICs require a stable voltage. Problems here can lead to erratic behavior.

Ensure your power supply meets the voltage and current requirements.

Use decoupling capacitors if needed to stabilize power.

Signal Noise and Propagation Delay

In complex circuits, signal interference and gate delay can affect performance.

Keep wiring neat and as short as possible.

Consider gate propagation delay when designing sequential circuits.
