Bus Tranceiver 8 bits

The bus transceiver is a technical element allowing you to connect a data/address bus (8 bits in this case) to a component. It's a bit like a big tap that allows communication to be established between two bus sections (or one bus and a component receiving parallel data).

The 3 state transceiver allows:

  • to block communication (high impedance)
  • to establish communication in one direction ( A --> B )
  • to establish communication in an opposite direction ( B --> A )

This device therefore allows data to be sent to a component via the data bus (to configure the component) -OR- to receive data over the data bus (emitted by the component) -OR- dissociate the component from the bus (High impedance, as if the component was not there).
