Understand the difference.
Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.
BUF
SymbolsNon-inverting logic buffer
Transfers a digital state through a non-inverting logic output stage.
- Drawing use
- Schematic
- Application
- Logic & signals
- Reference family
- Manufacturer
A distinction that matters
A buffer can provide drive capability without inversion; it is not a galvanic isolation barrier.
3STATE
SymbolsThree-state logic buffer
A digital output stage that can drive logical states or enter its documented high-impedance state.
- Drawing use
- Schematic
- Application
- Logic & signals
- Reference family
- Manufacturer
A distinction that matters
High impedance differs from driving logical zero; disabled outputs still have device-specific leakage and voltage limits.
