Signal pin overloaded
✕ errorcurrent/signal-over-source
What it looks like
U2.out is rated 0.02 A but its loads draw 0.05 A.
What it checks
A signal output's declared drive capability against the sum of what's hanging off it.
Why it matters
A logic pin asked for more current than it can source doesn't stop — it sags. The LED is dim, the next gate sees an ambiguous level, and the chip runs its driver at the edge of its spec for its whole life.
How to fix it
Buffer it: a transistor or gate driver between the signal and the load. Logic pins signal intent; transistors do work.
