What is Logic level in electronics sourcing?
The voltage ranges a digital pin reads as logic 0 and logic 1, set by the part's family (TTL, CMOS, LVCMOS, LVDS). Mismatched logic levels between connected parts make a design fail, so level compatibility is checked before any cross-reference is accepted.
