Two 8-bit back-to-back registers store data flowing in both directions between two bi-directional buses. Data applied to the inputs is entered and stored on the rising edge of the Clock (CPXX) provided that the Clock Enable (CEXX) is Low. The data is then present at the 3-State output buffers, but is only accessible when the Output Enable (OEXX) is Low. Data flow from ‘A’ inputs to ‘B’ outputs is the same as for ‘B’ inputs to ‘A’ outputs.
