Dual-Registered Transceiver Applications
Figure 13 illustrates how the 74F646A-649A and 74F651A-654A can
be used to either synchronize data transfer between two systems, or
pipeline data. Data is stored in a register, then, while retrieving more
data, the first data is read. When the second is available, it can
either be stored or read directly. Two slower systems can be
multiplexed into a high speed system in the same way.
Parity Bus Transceiver Applications
Figure 14 illustrates the functional density advantages of the Parity
Bus Series using the 74F657 in a typical microprocessor/data bus
transceiver application. Note the 74F245 + 74F280B version would
still require a 2-input AND gate and 3-State buffers for the PARITY
and ERROR outputs. And, of course, it would require an order of
magnitude higher input current than a single 74F657 would, and
would also introduce much higher capacitive loading (for both the
bus and the microcontroller).
