What is the circuit used in bus applications
Commonly used in the bus is a three-state gate circuit.
Circuit used in the bus application must be a three-state gate, when needed to open, you can output binary number, and when not in need to close, in a high-impedance state.
Is a TSL gate (tri-state gate output circuit).
Three-state output circuit is a high level, low level and high impedance three output state of the gate circuit, also known as three-state gate output circuit. In the solid state machine board circuit, "I / O" board circuit, in addition to the above several combination of gate circuits, three-state gate circuit is also essential.
Three-state gate circuits are TTL three-state gate circuit and CMOS three-state gate circuit.
