DESCRIPTION
The 74F2952 and 74F2953 are 8-bit registered transceivers. 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.
