This example shows how “Bus Transceiver” can be used to attach reading/writing components to a common data bus.
As long as switch “WR” is 0, the currently address RAM cell value is forwarded to output “O”. Change the value of input “ADR” to address different RAM cells.
In order to write a value into the RAM, enter the value to be written in input “I”, and set switch “WR” to 1. This enables the bus transceiver at “I” and sets the direction of the RAM’s bus transceiver to A->B.
