Understand the difference.
Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.
BUS-TR
SymbolsLogic bus transceiver
Drives data between two digital buses according to the selected direction and enable conditions.
- Drawing use
- Schematic
- Application
- Logic & signals
- Reference family
- Manufacturer
A distinction that matters
A transceiver supports a defined direction-control arrangement; it is not automatically a protocol controller or an isolator.
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.
